  • iPhone ASIHttpRequest - can't POST variables asynchronously

    - by Eamorr
    Greetings, I'm trying to simply POST data to a url using ASIHttpRequest. Here is my code: __block ASIHTTPRequest *request=[ASIHTTPRequest requestWithURL:url]; [request setPostBody:[NSMutableData dataWithData:[@"uname=Hello" dataUsingEncoding:NSUTF8StringEncoding]]]; [request setDelegate:self]; [request setCompletionBlock:^{ NSString *response=[request responseString]; UIAlertView *msg=[[UIAlertView alloc] initWithTitle:@"Response" message:response delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [msg show]; [msg release]; }]; [request setFailedBlock:^{ NSError *error =[request error]; }]; [request startAsynchronous]; Basically, my url is xxx.xxx.xxx.xxx/login.php, when I dump the PHP $_POST variable, I just get an empty array - i.e. no POST parameters are sent! The rest of the PHP is tested and working fine. I've looked through the allseeing-i.com documentation and examples and can't seem to resolve this problem. Any insight greatly appreciated. Many thanks in advance,

  • Persistent warning message about "initWithDelegate"!

    - by RickiG
    Hi This is not an actual Xcode error message, it is a warning that has been haunting me for a long time. I have found no way of removing it and I think I maybe have overstepped some unwritten naming convention rule. If I build a class, most often extending NSObject, whose only purpose is to do some task and report back when it has data, I often give it a convenience constructor like "initWithDelegate". The first time I did this in my current project was for a class called ISWebservice which has a protocol like this: @protocol ISWebserviceDelegate @optional - (void) serviceFailed:(NSError*) error; - (void) serviceSuccess:(NSArray*) data; @required @end Declared in my ISWebservice.h interface, right below my import statements. I have other classes that uses a convenience constructor named "initWithDelegate". E.g. "InternetConnectionLost.h", this class does not however have its methods as optional, there are no @optional @required tags in the declaration, i.e. they are all required. Now my warning pops up every time I instantiate one of these Classes with convenience constructors written later than the ISWebservice, so when utilizing the "InternetConnectionLost" class, even though the entire Class owning the "InternetConnectionLost" object has nothing to do with the "ISWebservice" Class, no imports, methods being called, no nothing, the warning goes: 'ClassOwningInternetConnectionLost' does not implement the 'ISWebserviceDelegate' protocol I does not break anything, crash at runtime or do me any harm, but it has begun to bug me as I near release. Also, because several classes use the "initWithDelegate" constructor naming, I have 18 of these warnings in my build results and I am getting uncertain if I did something wrong, being fairly new at this language. Hope someone can shed a little light on this warning, thank you:)

  • NSFetchedResultsController: changing predicate not working?

    - by icerelic
    Hi, I'm writing an app with two tables on one screen. The left table is a list of folders and the right table shows a list of files. When tapped on a row on the left, the right table will display the files belonging to that folder. I'm using Core Data for storage. When the selection of folder changes, the fetch predicate of the right table's NSFetchedResultsController will change and perform a new fetch, then reload the table data. I used the following code snippet: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"list = %@",self.list]; [fetchedResultsController.fetchRequest setPredicate:predicate]; NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } [table reloadData]; However the fetch results are still the same. I've NSLog'ed "predicate" before and after the fetch, and they were correct with updated information. The fetch results stay the same as initial fetch (when view is loaded). I'm not very familiar with the way Core Data fetches objects (is there a caching system?), but I've done similar things before(changing predicates, re-fetching data, and refreshing table) with single table views and everything went well. If someone could gave me a hint I would be very appreciated. Thanks in advance.

  • How to switch from Core Data automatic lightweight migration to manual?

    - by Jaanus
    My situation is similar to this question. I am using lightweight migration with the following code, fairly vanilla from Apple docs and other SO threads. It runs upon app startup when initializing the Core Data stack. NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; NSError *error = nil; NSString *storeType = nil; if (USE_SQLITE) { // app configuration storeType = NSSQLiteStoreType; } else { storeType = NSBinaryStoreType; } persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; // the following line sometimes crashes on app startup if (![persistentStoreCoordinator addPersistentStoreWithType:storeType configuration:nil URL:[self persistentStoreURL] options:options error:&error]) { // handle the error } For some users, especially with slower devices, I have crashes confirmed by logs at the indicated line. I understand that a fix is to switch this to manual mapping and migration. What is the recipe to do that? The long way for me would be to go through all Apple docs, but I don't recall there being good examples and tutorials specifically for schema migration.

  • Wordpress XML-RPC call from Objective C: wp.newComment

    - by radesix
    I'm using Eric Czarny's Cocoa XML-RPC framework to make a call to the Wordpress API's. I've downloaded the sample app from Wordpress which gives some good examples. Unfortunately the good examples are for every call EXCEPT wp.newComment. I'm trying to post a comment using the code below and I keep getting an error with a localized description that tells me to check my input parameters. I've checked and rechecked and I don't understand what is wrong. Any ideas? NSDictionary *commentStructure = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithInt:0], @"comment_parent", @"xmlrpc anonymous comments plugin now enabled", @"content", @"Test Author", @"author", @"http://iphone.someurl.com", @"author_url", @"[email protected]", @"author_email", nil]; NSArray *args = [NSArray arrayWithObjects:[NSNumber numberWithInt:0], @"", @"", [NSNumber numberWithInt:[self.parentFeedItem.postID intValue]], commentStructure, nil]; // the param(s) NSString *server = [[[NSString alloc] initWithString:@"http://www.someurl.com/xmlrpc.php"] autorelease]; // the server NSString *method = [[[NSString alloc] initWithString:@"wp.newComment"] autorelease]; // the method XMLRPCRequest *request = [[XMLRPCRequest alloc] initWithHost:[NSURL URLWithString:server]]; [request setMethod:method withObjects:args]; id response = [self executeXMLRPCRequest:request]; [request release]; if( [response isKindOfClass:[NSError class]] ) { //return nil; NSLog(@"There was a problem"); NSLog([response localizedDescription]); }

  • Calculating File size before download

    - by sagar
    Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  • Why would delaying a thread response fix view corruption?

    - by Beth S
    6 times out of 10 my very simple iPhone app is getting a corrupted display on launch or crashes randomly. But it behaves fine in the simulator. The display corruption looks like mis-colored fonts, out of place font text, wrong background colors, etc. I've found a strange work-around.. when my thread delays by 2 seconds before calling the "done" notification, everything works swimmingly. The thread reads a web page and the "done" notification loads up a PickerView with strings. So what gives? Can I not safely initiate a threaded task from viewDidLoad? - (void) loadWebPage:(NSString *)urlAddition { NSAutoreleasePool *subPool = [[NSAutoreleasePool alloc] init]; NSString *pageSource; NSError *err; NSString *urlString = [NSString stringWithString:@"http://server/%@", urlAddition]; pageSource = [NSString stringWithContentsOfURL:[NSURL URLWithString: urlString] encoding:NSUTF8StringEncoding error:&err]; [NSThread sleepForTimeInterval:2.0]; // THIS STOPS THE DISPLAY CORRUPTION [[NSNotificationCenter defaultCenter] postNotificationName:@"webDoneNotification" object:nil]; [subPool drain]; } - (void) webDoneNotification: (NSNotification *)pNotification { [mediaArray release]; mediaArray = [[NSArray arrayWithObjects: [NSString stringWithString:@"new pickerview text"], nil] retain]; [mediaPickerView reloadAllComponents]; [mediaPickerView selectRow:0 inComponent:0 animated:NO]; } - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { mediaArray = [[NSArray arrayWithObjects: [NSString stringWithString:@"init pickerview text"], nil] retain]; if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; myWebThread = [[WebThread alloc] initWithDelegate:self]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(webDoneNotification:) name:@"webDoneNotification" object:nil]; [myWebThread performSelectorInBackground:@selector(loadWebPage:) withObject:@""]; } Thanks! Update: Even a delay of 0.1 seconds is enough to completely fix the problem.

  • iPhone Twitter Integration: Validating login.

    - by Mr. McPepperNuts
    The following code posts to twitter: NSString *compoundLoginString = [NSString stringWithFormat:@"http://%@:%@@twitter.com/statuses/update.xml",extractedUsername, extractedPassword]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:compoundLoginString] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0]; // The text to post NSString *msg = tweetText; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[[NSString stringWithFormat:@"status=%@", msg] dataUsingEncoding:NSASCIIStringEncoding]]; NSURLResponse *response; NSError *error; if ([NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error] != nil){ [self postSuccessfulAlert]; }else{ [self postNotSuccessfulAlert]; } I am curious as to how I could check if the username and password is correct before proceeding to the above piece of code. I found the following code in a tutorial, but am unsure how I would implement or call this function. - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { if ([challenge previousFailureCount] == 0) { NSURLCredential *newCredential; newCredential=[NSURLCredential credentialWithUser:[self username] password:[self password] persistence:NSURLCredentialPersistenceNone]; [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; } else { [[challenge sender] cancelAuthenticationChallenge:challenge]; // inform the user that the user name and password // in the preferences are incorrect NSLog(@"Invalid Username or Password"); } } Any ideas?

  • Google Translate API for iPhone - UTF8 problem in Chinese Translation

    - by Sky Chen
    I've tested a workable translation API url by: http://translate.google.com/translate_a/t?client=t&text=%E5%BB%A3%E5%A0%B4&langpair=zh|zh-CN And it returns the correct result as the following which is in JSON format: {"sentences":[{"trans":"??","orig":"??","translit":"Guangchang"}],"src":"zh-CN"} However, when I try to use this function in XCode, I experienced this problem ... Here is my code: NSData *data; NSString *urlPath = [NSString stringWithFormat:@"/translate_a/t?client=t&text=%@&langpair=zh|zh-CN",qText]; NSURL *url = [[NSURL alloc] initWithScheme:@"http" host:@"translate.google.com" path:urlPath]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:url]; [request setHTTPMethod:@"GET"]; NSURLResponse *response; NSError *error; data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; //Problem's here. It returns nil. NSLog(result); Initially I guessed it's encoding problem so I tried other encoding as well (NSISOLatin1StringEncoding) , but I got wrong answer: {"sentences":[{"trans":"ã ","orig":"ã ","translit":"Tu¨¯ "}],"src":"zh-CN"} Does anyone know how to solve this problem? Thank you very much!

  • Modifying NSMutableDictionary from a single index format into nested (array within array)

    - by Michael Robinson
    I need to take the member ID off the top of this and create an array inside that contains the rest of the JSON return. Here is my JSON return. [{"F_Name_VC":"Frank", "L_Name_VC":"Johnson", "userid":"18", "age":"23", },] After it is json-deserialized it looks like this: I need convert it to be transformed into this, with children sub-array: Someone else posted a similar question but without the fact that it was coming from a JSON deserialization. There were two answers but no conclusion to the question. (Answer 1): NSDictionary *item1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@" member",[NSNumber numberWithInt:3],nil] forKeys:[NSArray arrayWithObjects:@"Title",@"View",nil]]; Answer (2): NSMutableArray *Rows = [NSMutableArray arrayWithCapacity: 1]; for (int i = 0; i < 4; ++i) { NSMutableArray *theChildren = [NSMutableArray arrayWithCapacity: 1]; [theChildren addObject: [NSString stringWithFormat: @"tester %d", i]]; NSString *aTitle = [NSString stringWithFormat: @"Item %d", i]; NSDictionary *anItem = [NSDictionary dictionaryWithObjectsAndKeys: aTitle, @"Title", theChildren, @"Children"]; [Rows addObject: anItem]; } NSDictionary *Root = [NSDictionary withObject: Rows andKey: @"Rows"]; Here is my JSON return and save code: NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; if (dict) { rowsArray = [dict objectForKey:@"member"]; [rowsArray retain]; } Thanks in advance. Every tutorial on JSON only shows a simple array being returned, never with children..It's driving me crazy trying to figure this out.

  • How to update the user profile through tokenid when a particular user logs in using his username and password

    - by Rani
    i have an application in which when the user enters his username and password in the login form , his username and password are submitted to the server database for validation and if he is a valid user a tokenid is generated for him through JSON response and he is allowed to log in.this is the JSON response that i get in the console when a valid user log in through the log in form : {"TokenID":"kaenn43otO","isError":false,"ErrorMessage":"","Result":[{"UserId":"164","FirstName":"Indu","LastName":"nair","Email":"[email protected]","ProfileImage":null,"ThumbnailImage":null,"DeviceInfoId":"22"}],"ErrorCode":900} 2011-06-24 11:56:57.639 Journey[5526:207] this is token id:kaenn43otO so when the same user wants to update his profile by clicking on the update tab using the tokenid So that if he want he can his firstname,lastname,password,email.etc.i i have done the following code to update the user profile using tokenid but it does not work.i get tokenid when the user log in and this tokenid i have to pass to other class: this is my code to update user profile: -(void)sendRequest { //this is the class in which i get the tokenid and i am passing it to this class apicontroller *apitest = [[apicontroller alloc]init]; NSString *tokentest = apitest.tokenapi; NSString *post = [NSString stringWithFormat:@"Token=%@&firstname=%@&lastname=%@&Username=%@&Password=%@&Email=%@",tokentest,txtfirstName.text,txtlast.text,txtUserName.text,txtPassword.text,txtEmail.text]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSLog(@"%@",postLength); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://192.168.0.1:96/JourneyMapperAPI?RequestType=Register&Command=SET"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { webData = [[NSMutableData data] retain]; NSLog(@"%@",webData); [theConnection start]; } else { } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [webData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [webData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; [webData release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; NSLog(@"%@",loginStatus); [loginStatus release]; [connection release]; [webData release]; } -(IBAction)click:(id)sender { [self sendRequest]; } this is my apicontroller.m file in which i am creating login form so that user login and in this page tokenid is generated -(void)sendRequest { UIDevice *device = [UIDevice currentDevice]; NSString *udid = [device uniqueIdentifier]; //NSString *sysname = [device systemName]; NSString *sysver = [device systemVersion]; NSString *model = [device model]; NSLog(@"idis:%@",[device uniqueIdentifier]); NSLog(@"system nameis :%@",[device systemName]); NSLog(@"System version is:%@",[device systemVersion]); NSLog(@"System model is:%@",[device model]); NSLog(@"device orientation is:%d",[device orientation]); NSString *post = [NSString stringWithFormat:@"Loginkey=%@&Password=%@&DeviceCode=%@&Firmware=%@&IMEI=%@",txtUserName.text,txtPassword.text,model,sysver,udid]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSLog(@"%@",postLength); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://192.168.0.1:96/JourneyMapperAPI?RequestType=Login"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { webData = [[NSMutableData data] retain]; NSLog(@"%@",webData); } else { } } //to select username and password from database. -(void)check { //app.journeyList = [[NSMutableArray alloc]init]; [self createEditableCopyOfDatabaseIfNeeded]; NSString *filePath = [self getWritableDBPath]; sqlite3 *database; if(sqlite3_open([filePath UTF8String], &database) == SQLITE_OK) { const char *sqlStatement = "SELECT Username,Password FROM UserInformation where Username=?

  • Core data migration failing with "Can't find model for source store" but managedObjectModel for source is present

    - by Ira Cooke
    I have a cocoa application using core-data, which is now at the 4th version of its managed object model. My managed object model contains abstract entities but so far I have managed to get migration working by creating appropriate mapping models and creating my persistent store using addPersistentStoreWithType:configuration:options:error and with the NSMigratePersistentStoresAutomaticallyOption set to YES. NSDictionary *optionsDictionary = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; NSURL *url = [NSURL fileURLWithPath: [applicationSupportFolder stringByAppendingPathComponent: @"MyApp.xml"]]; NSError *error=nil; [theCoordinator addPersistentStoreWithType:NSXMLStoreType configuration:nil URL:url options:optionsDictionary error:&error] This works fine when I migrate from model version 3 to 4, which is a migration that involves adding attributes to several entities. Now when I try to add a new model version (version 5), the call to addPersistentStoreWithType returns nil and the error remains empty. The migration from 4 to 5 involves adding a single attribute. I am struggling to debug the problem and have checked all the following; The source database is in fact at version 4 and the persistentStoreCoordinator's managed object model is at version 5. The 4-5 mapping model as well as managed object models for versions 4 and 5 are present in the resources folder of my built application. I've tried various model upgrade paths. Strangely I find that upgrading from an early version 3 - 5 works .. but upgrading from 4 - 5 fails. I've tried adding a custom entity migration policy for migration of the entity whose attributes are changing ... in this case I overrode the method beginEntityMapping:manager:error: . Interestingly this method does get called when migration works (ie when I migrate from 3 to 4, or from 3 to 5 ), but it does not get called in the case that fails ( 4 to 5 ). I'm pretty much at a loss as to where to proceed. Any ideas to help debug this problem would be much appreciated.

I can set and retrieve values using the selectors, but if I try and use KVC (ie setValue: forKey: ) everything goes bad and says my StatTracker class is not KVC compliant: valueForUndefinedKey:]: the entity StatTracker is not key value coding-compliant for the key "timesLauched".' 2010-05-18 15:55:08.573 here's the code that is triggering it: NSArray *statTrackerArray = [[NSArray alloc] init]; statTrackerArray = [[CoreDataSingleton sharedCoreDataSingleton] getStatTracker]; NSNumber *number1 = [[NSNumber alloc] init]; number1 = [NSNumber numberWithInt:(1 + [[(StatTracker *)[statTrackerArray objectAtIndex:0] valueForKey:@"timesLauched"] intValue])]; [(StatTracker *)[statTrackerArray objectAtIndex:0] setValue:number1 forKey:@"timesLaunched" ]; NSError *error; if (![[[CoreDataSingleton sharedCoreDataSingleton] managedObjectContext] save:&error]) { NSLog(@"error writing to db"); } Not sure if this is enough code for you folks let me know what you need if you do need more. This would be so sweet if I could use KVC because I could then abstract all this stat tracking stuff into a single method call with a string argument for the value in question. At least that is what I hope to accomplish here. I'm actually now understanding the power of KVC but now I'm just trying to figure out how to make it work. Thanks! Nick

  • Core Data @sum aggregate

    - by nasim
    I am getting an exception when I try to get @sum on a column in iPhone Core-Data application. My two models are following - Task model: @interface Task : NSManagedObject { } @property (nonatomic, retain) NSString * taskName; @property (nonatomic, retain) NSSet* completion; @end @interface Task (CoreDataGeneratedAccessors) - (void)addCompletionObject:(NSManagedObject *)value; - (void)removeCompletionObject:(NSManagedObject *)value; - (void)addCompletion:(NSSet *)value; - (void)removeCompletion:(NSSet *)value; @end Completion model: @interface Completion : NSManagedObject { } @property (nonatomic, retain) NSNumber * percentage; @property (nonatomic, retain) NSDate * time; @property (nonatomic, retain) Task * task; @end And here is the fetch: NSFetchRequest *request = [[NSFetchRequest alloc] init]; request.entity = [NSEntityDescription entityForName:@"Task" inManagedObjectContext:context]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"taskName" ascending:YES]; request.sortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSError *error; NSArray *results = [context executeFetchRequest:request error:&error]; NSArray *parents = [results valueForKeyPath:@"taskName"]; NSArray *children = [results valueForKeyPath:@"[email protected]"]; NSLog(@"%@ %@", parents, children); [request release]; [sortDescriptor release]; The exception is thrown at the fourth line from bottom.

Thanks.

  • Extract attributes from NSManagedObject array.

    - by Pavel Peroutka
    NSFetchRequest *req = [NSFetchRequest init]; NSEntityDescription *descr = [NSEntityDescription entityForName:@"City" inManagedObjectContext:context]; [req setEntity:descr]; NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"streetName" ascending:YES]; [req setSortDescriptors:[NSArray arrayWithObject:sort]]; [sort release]; //fetch NSError *error; NSArray *result = [context executeFetchRequest:req error:&error]; //extract names NSMutableArray *streets = [[NSMutableArray alloc] init]; for () { ??? = [array objectAtIndex:i]; [streets addObject:name]; } I expected Core Data to be little more intuitive. I am new in it and I could use some help. I fetched all objects(rows) from the entity (table) City. Now I have an array of objects. From the array I need to extract the attribute “streetName” to an array which will feed the picker. I figured I need to do it in the loop but I could not figure out the way to do it. Please help. I have a background with SQL but Core Data is still a big mystery to me. Is there any publication which would take a SQL statement and show comparable Core Data syntax? Thanks.

  • How can I implement a volume meter for a song currently playing? (iPhone OS 3.1.3)

    - by Adam
    Hi i'm very new to core audio and I just would like some help in coding up a little volume meter for whatever's being outputted through headphones or built-in speaker. Like a dB meter. I have the following code, and have been trying to go through the apple source project "SpeakHere", but it's a nightmare trying to go through all that, without knowing how it works first... Could anyone shed some light? Here's the code I have so far... (void)displayWaveForm { while (musicIsPlaying == YES { NSLog(@"%f",sizeof(AudioQueueLevelMeterState)); } } (IBAction)playMusic { if (musicIsPlaying == NO) { NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/track7.wav",[[NSBundle mainBundle] resourcePath]]]; NSError *error; music = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; music.numberOfLoops = -1; music.volume = 0.5; [music play]; musicIsPlaying = YES; [self displayWaveForm]; } else { [music pause]; musicIsPlaying = NO; } }

  • iPhone Core Data does not refresh table

    - by Brian515
    Hi all, I'm trying to write an application with Core Data, and I have been able to successfully read and write to the core data database. However, if I write to the database in one view controller, my other view controllers will not see the change until the app is closed then reopened again. This is really frustrating. I'm not entirely sure how to get the refresh - (void)refreshObject:(NSManagedObject *)object mergeChanges:(BOOL)flag method to work. How do I get a reference to my managed object? Anyways, here's the code I'm using to read the data back. This is in the viewDidLoad method. NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Website" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"siteName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if(mutableFetchResults == nil) { //Handle the error } [self setNewsTitlesArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; [newsSourcesTableView reloadData]; Thanks for help in advance!

  • Is NSManagedObjectContext autosaved or am I looking at NSFetchedResultsController's cache?

    - by Andreas
    I'm developing an iPhone app where I use a NSFetchedResultsController in the main table view controller. I create it like this in the viewDidload of the main table view controller: NSSortDescriptor *sortDescriptorDate = [[NSSortDescriptor alloc] initWithKey:@"date" ascending:YES]; NSSortDescriptor *sortDescriptorTime = [[NSSortDescriptor alloc] initWithKey:@"start" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptorDate,sortDescriptorTime, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; [sortDescriptorDate release]; [sortDescriptorTime release]; [sortDescriptors release]; controller = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:context sectionNameKeyPath:@"date" cacheName:nil]; [fetchRequest release]; NSError *error; BOOL success = [controller performFetch:&error]; Then, in a subsequent view, I create a new object on the context: TestObject *testObject = [NSEntityDescription insertNewObjectForEntityForName:@"TestObject" inManagedObjectContext:context]; The TestObject has several related object which I create in the same way and add to the testObject using the provided add...Objects methods. Then, if before saving the context, I press cancel and go back to the main table view, nothing is shown as expected. However, if I restart the app, the object I created on the context shows in the main table view. How come? At first, I thought it was because the NSFetchedResultsController was reading from the cache, but as you can see I set this to nil just to test. Also, [context hasChanges] returns true after I restart. What am I missing here?

  • Fetching Core Data for Tableview on iPhone - Tutorial leaves me with crashes when adding items to a

    - by Gordon Fontenot
    Been following the Core Data tutorial on Apple's developer site, and all is good until I have to add something to the fetched store. I am getting this error after a successful build and load when I try to add a new item to the list: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted). Due to the fact that the fetch goes through fine, and that if I replace the fetching with eventList = [[NSMutableArray alloc] init] it works as expected (without persistance, of course), I am led to believe that the problem comes from not creating the Mutable Array correctly. Here's the problematic part of the code: NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"creationDate" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [sortDescriptor release]; NSError *error; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults = nil) { //Handle the error } [self setEventList:mutableFetchResults]; [mutableFetchResults release]; [request release]; I have tried switching the NSArrays in the second chunk out with NSMutableArrays, but I still get the same error. For reference, the section of code that is throwing the error when I try adding an entry is here: [eventList insertObject:event atIndex:0]; NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES]; it errors out at the insertRowsAtIndexPaths call. Thanks in advance for any help

    I have a plist file in my resources group in xcode. I am trying to copy this into my documents directory on app launch. I am using the following code (taken from a sqlite tutorial): BOOL success; NSError *error; NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath = [documentsDirectory stringByAppendingString:@"ActiveFeedsPlist.plist"]; success = [fileManager fileExistsAtPath:filePath]; if (success) return; NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingFormat:@"ActiveFeedsPlist.plist"]; success = [fileManager copyItemAtPath:path toPath:filePath error:&error]; if (!success) { NSAssert1(0, @"Failed to copy Plist.

  • iPhone NSCFString leaks in fetchRequest

    - by camilo
    In the following code: - (NSMutableArray *) fetchNotesForGroup: (NSString *)groupName { // Variables declaration NSMutableArray *result; NSFetchRequest *fetchRequest; NSEntityDescription *entity; NSSortDescriptor *sortDescriptor; NSPredicate *searchPredicate; NSError *error = nil; // Creates the fetchRequest and executes it fetchRequest = [[[NSFetchRequest alloc] init] autorelease]; entity = [NSEntityDescription entityForName:@"Note" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"noteName" ascending:YES] autorelease]; [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]]; [fetchRequest setReturnsDistinctResults:YES]; searchPredicate = [NSPredicate predicateWithFormat:@"categoryName like %@", groupName]; [fetchRequest setPredicate:searchPredicate]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObject:@"noteName"]]; result = [[managedObjectContext executeFetchRequest:fetchRequest error:&error] mutableCopy]; // Variables release return result; } ... I Fetch notes for a given categoryName. When I'm running Instruments, it says that a NSCFString is leaking. I know leaks are mean for iPhone developers... but I don't have any idea on how to plug this one. Any clues? All help is welcome. Thanks a lot!

    Hi, I have made a php web services that takes the username and password from iPhone application and saves the data in the users table. I call that web service from my button touchup event like this: NSLog(userName.text); NSLog(password.text); NSString * dataTOB=[userName.text stringByAppendingString:password.text]; NSLog(dataTOB); NSData * postData=[dataTOB dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSLog(postLength); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://localhost:8888/write.php"]]; [request setURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLResponse *response; NSError *error; [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; if(error==nil) NSLog(@"Error is nil"); else NSLog(@"Error is not nil"); NSLog(@"success!"); I am getting nothing from Iphone side into the web service and I am unable to understand why this is happening. Although i debugged and found that everything is fine at the iphone application level but the call to the web service doesn't works as expected...... Please suggest..... Thanks Ashish

  • UIImage - should be loaded with [UIImage imageNamed:@""] or not ?

    - by sagar
    Hello ! every one. I am having number of images with in my application. ( images more than 50 - approximately & it can extend according to client's need ) Each image are very large round about - 1024 x 768 & 150 dpi Now, I have to add all this images in a scroll view & display it. Ok, My question is as follows. According to me there are two options of loading large images imageNamed:@"" load asynchronously when viewDidLoad Called. Which is more preferable ? imgModel.image=[UIImage imageNamed:[dMain valueForKey:@"imgVal"]]; or like this. NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:lblModelName.text ofType:@"png"] isDirectory:NO]; NSURLRequest *req=[NSURLRequest requestWithURL:ur cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:40]; [ur release]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self]; if(con){ myWebData=[[NSMutableData data] retain]; } else { } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"ImageView Ref From - %@",imgV); // my image view & set image imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; }
