  • Is Fast Enumeration messing with my text output?

    - by Dan Ray
    Here I am iterating through an array of NSDictionary objects (inside the parsed JSON response of the EXCELLENT MapQuest directions API). I want to build up an HTML string to put into a UIWebView. My code says: for (NSDictionary *leg in legs ) { NSString *thisLeg = [NSString stringWithFormat:@"<br>%@ - %@", [leg valueForKey:@"narrative"], [leg valueForKey:@"distance"]]; NSLog(@"This leg's string is %@", thisLeg); [directionsOutput appendString:thisLeg]; } The content of directionsOutput (which is an NSMutableString) contains ALL the values for [leg valueForKey:@"narrative"], wrapped up in parens, followed by a hyphen, followed by all the parenthesized values for [leg valueForKey:@"distance"]. So I put in that NSLog call... and I get the same thing there! It appears that the for() is somehow batching up our output values as we iterate, and putting out the output only once. How do I make it not do this but instead do what I actually want, which is an iterative output as I iterate? Here's what NSLog gets. Yes, I know I need to figure out NSNumberFormatter. ;-) This leg's string is ( "Start out going NORTH on INFINITE LOOP.", "Turn LEFT to stay on INFINITE LOOP.", "Turn RIGHT onto N DE ANZA BLVD.", "Merge onto I-280 S toward SAN JOSE.", "Merge onto CA-87 S via EXIT 3A.", "Take the exit on the LEFT.", "Merge onto CA-85 S via EXIT 1A on the LEFT toward GILROY.", "Merge onto US-101 S via EXIT 1A on the LEFT toward LOS ANGELES.", "Take the CA-152 E/10TH ST exit, EXIT 356.", "Turn LEFT onto CA-152/E 10TH ST/PACHECO PASS HWY.

  • Adjust size of MPMediaPickerController's view ?

    - by Mr.Gando
    In my application I don't use the upper bar that displays Wi-Fi/Date/Time because it's a game. However I need to be able to let my user to pick his music, so I'm using a MPMediaPickerController. The problem is, that when I present my controller, the controller ends up leaving a 10 pixels ( aprox ) bar at the top of the screen, just in the place the Wi-Fi/Date/Time bar, should be present. Is there a way I could make my MPMediaPickerController bigger ? or to be presented upper in the screen ? // Configures and displays the media item picker. - (void) showMediaPicker: (id) sender { MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio]; [[picker view] setFrame:CGRectMake(0, 0, 320, 480)]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"AddSongsPrompt", @"Prompt to user to choose some songs to play"); [self presentModalViewController:picker animated: YES]; [picker release]; } There I tried to set the size to 320x480 but no luck, the picker is still presented and leaves a space in the upper part of the screen, could anyone help me ? Btw, here's how it looks: I have asked a bit, and people told me this could indeed be a bug, what do you guys think ?

  • Memory problem with basic UITableView when scrolling

    - by Sheehan Alam
    I have a very simple UITableView that has 3 sections, and 3 rows per section. #pragma mark - #pragma mark UITableView delegate methods - (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tblView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... return cell; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tblView { if (tblView == self.tableView) { return 3; } else { return 1; } } Everything shows up fine, but as soon as I scroll my application crashes and my debugger tells me: * -[ProfileViewController tableView:cellForRowAtIndexPath:]: message sent to deallocated instance 0x5ae61b0 I'm not exactly sure what I am doing wrong.

  • Elegant Algorithm for Parsing Data Stream Into Record

    - by Matt Long
    I am interfacing with a hardware device that streams data to my app over Wifi. The data is streaming in just fine. The data contains a character header (DATA:) that indicates a new record has begun. The issues is that the data I receive doesn't necessarily fall on the header boundary, so I have to capture the data until what I've captured contains the header. Then, everything that precedes the header goes into the previous record and everything that comes after it goes into a new record. I have this working, but wondered if anyone has done this before and has a good computer-sciencey way to solve the problem. Here's what I do: Convert the NSData of the current read to an NSString Append the NSString to a placeholder string Check placeholder string for the header (DATA:). If the header is not there, just wait for the next read. If the header exists, append whatever precedes it to a previous record placeholder and hand that placeholder off to an array as a complete record that I can further parse into fields. Take whatever shows up after the header and place it in the record placeholder so that it can be appended to in the next read. Repeat steps 3 - 5. Let me know if you see any flaws with this or have a suggestion for a better way. Seems there should be some design pattern for this, but I can't think of one. Thanks.

  • How do I split an NSString by each character in the string?

    - by Robert Höglund
    I have the following code, which works as I expect. What I would like to know if there is an accepted Cocoa way of splitting a string into an array with each character of the string as an object in an array? - (NSString *)doStuffWithString:(NSString *)string { NSMutableArray *stringBuffer = [NSMutableArray arrayWithCapacity:[string length]]; for (int i = 0; i < [string length]; i++) { [stringBuffer addObject:[NSString stringWithFormat:@"%C", [string characterAtIndex:i]]]; } // doing stuff with the array return [stringBuffer componentsJoinedByString:@""]; }

  • NSTableView is not showing my data. Why is that happening?

    - by lampShade
    I'm making a "simple" to-do-list project and running into a few bumps in the road. The problem is that my NSTableView is NOT showing the data from the NSMutableArray "myArray" and I don't know why that is. Can someone point out my mistake? /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { NSString *myString = [textField stringValue]; NSLog(@"my stirng is %@",myString); myArray = [[NSMutableArray alloc] initWithCapacity:100]; [myArray addObject:myString]; } - (int)numberOfRowsInTableView:(NSTableView *)aTableView { return [myArray count]; } - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex { return [myArray objectAtIndex:rowIndex]; } -(id)init { [super init]; [tableView setDataSource:self]; [tableView setDelegate:self]; NSLog(@"init"); return self; } @end

  • NSPredicate error/behaving differently on 10.5 vs 10.6

    - by Tristan
    I am using a NSPredicate to determine if an entered email address is valid. On 10.6 it works perfectly as expected. I recently decided to get my app going on 10.5 and this is the only thing that doesn't work. The error i get is as follows: "Can't do regex matching, reason: Can't open pattern U_MALFORMED_SET (string [email protected], pattern ([\w-+]+(?:\.[\w-+]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}), case 0, canon 0)" The code im using is as follows: NSString *regex = @"([\\w-+]+(?:\\.[\\w-+]+)*@(?:[\\w-]+\\.)+[a-zA-Z]{2,7})"; NSPredicate *regextest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex]; if ([regextest evaluateWithObject:[userEmail objectValue]] == YES) Does anyone know why this isn't working on 10.5? And how I might get it working or be able to do this test in a way compatible for both 10.5 and 10.6?

  • show UIAlertView when In app purchase is in progress

    - by edie
    Hi... I've added an UIAlertView that has UIActivityIndicatior as a subview on my application. This alertView only show when the purchase is in progress. I've put my alert view in this way in my StoreObserver: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { for (SKPaymentTransaction *transaction in transactions) { switch (transaction.transactionState) { case SKPaymentTransactionStatePurchasing: [self stillPurchasing]; // this creates an alertView and shows break; case SKPaymentTransactionStatePurchased: [self completeTransaction:transaction]; break; case SKPaymentTransactionStateFailed: [self failedTransaction:transaction]; break; case SKPaymentTransactionStateRestored: [self restoreTransaction:transaction]; break; default: break; } } } - (void) stillPurchasing { UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"In App Purchase" message: @"Processing your purchase..." delegate: nil cancelButtonTitle: nil otherButtonTitles: nil]; self.alertView = alert; [alert release]; UIActivityIndicatorView *ind = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhiteLarge]; self.indicator = ind; [ind release]; [self.indicator startAnimating]; [self.alertView addSubview: self.indicator]; [self.alertView show]; } When I tap my the buy button this UIAlertView shows together with my UIActivityIndicator.. But when the transaction completes the alertView still on the top of the view and the Indicator was the only one that was removed. My question was how should I release the alertView? Or where/When should I release it. I've added these command to release my alertView and Indicator on these cases: case SKPaymentTransactionStatePurchased: case SKPaymentTransactionStateFailed: case SKPaymentTransactionStateRestored: [self.indicator stopAnimating]; [self.indicator removeFromSuperview]; [self.alertView release]; [self.indicator release]; I've only added the alertView to show that the purchasing was still in progress. Any suggestion to create any feedback to users will be thankful for me.. Thanks

  • Discover the environment and relative path of the running application

    - by Shyam
    Hi, While playing with RubyCocoa, I keep progressing with my idea for my application. Because my application will be going to use configuration files, I would like to know how I discover the relative path to store these inside my application structure (or if a better idea emerges, please elaborate also the "why"). Also good for me to know is to discover environment variables, such as operating system version, the amount of memory that is available and such. Hyperlinks would be awesome too. Please notice I use RubyCocoa and thank you for your feedback, comments and answers!

  • AppDelegate viewController memory leak?

    - by fuzzygoat
    I am just curious with regards to the correct way to create a view controller programatically. When I compile this code with the static analyser I get a leak (as you would expect) from the alloc. Should I just leave it as it needs to stay until the app exits anyways, or is there a cleaner way? - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSLog(@"UIApplication application:"); RectViewController *myController = [[RectViewController alloc] init]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; return YES; } cheers Gary

  • Change UIImagePicker Navigation Bar style to blue

    - by vodkhang
    All of my view has a blue navigation bar but when I want user to choose a photo, the UIImagePicker is black. I tried to set the navigation bar of UIImagePickerController to blue using UIBarStyleDefault but it does not work for me, the color is still black. I tried with other UIBarStyle like UIBarStyleBlack and UIBarStyleOpaque as well but it doesn't change the navigation bar of the picker anyway. Here is my code // Let the user choose a new photo. UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.navigationBar.barStyle = UIBarStyleDefault; [self presentModalViewController:imagePicker animated:YES]; [imagePicker release];

  • UITableViewCell repeating problem

    - by cannyboy
    I have a UItableview with cells. Some cells have uilabels and some have uibuttons. The UIbuttons are created whenever the first character in an array is "^". However, the uibuttons repeat when i scroll down (appearing over the uilabel).. and then multiply over the uilabels when I scroll up. Any clues why? My voluminous code is below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { const NSInteger LABEL_TAG = 1001; UILabel *label; UIButton *linkButton;

  • How do you delete rows from UITableView?

    - by James
    This has been bugging me for hours now and i have not been able to figure it out. I am importing data into a tableview using core data and NSMutableArray. As shown below.

This method here works apart from the fact that the results over a certain distance are still in the table, they are just not graphically visible. I am led to believe that i have to carry out the filtering process before the formatting the table but i can not seem to do this. Please help. My xcode skills are not brilliant so code suggestions would be helpfull.

  • How do I share an NSArrayController between two nib files?

    - by Tom Dalling
    I have an array of images, and two nib files. One nib file has a window that displays the images in an NSTableView. The other nib has a window that draws the array of images into an NSView, and also draws a highlight over the images that are selected. The array of images is controlled by an NSArrayController. I'm having trouble getting the two nibs to share the NSArrayController. I would have two separate NSArrayControllers bound to the same content, but I also want both nibs to share the controller's selection; that is, if you select an image in the table window, it also becomes selected in the other window. Is there a standard way to do this?

  • NSMutableArray can't be added to

    - by Dan Ray
    I've had this sort of problem before, and it didn't get a satisfactory answer. I have a viewcontroller with a property called "counties" that is an NSMutableArray. I'm going to drill down a navigation screen to a view that is about selecting the counties for a geographical search. So the search page drills down to the "select counties" page. I pass NSMutableArray *counties to the second controller as I push the second one on the navigation stack. I actually set that second controller's "selectedCounties" property (also an NSMutableArray) with a pointer to my first controller's "counties", as you'll see below. When I go to addObject to that, though, I get this: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '*** -[NSCFArray insertObject:atIndex:]: mutating method sent to immutable object' Here's my code: in SearchViewController.h: @interface SearchViewController : UIViewController { .... NSMutableArray *counties; } .... @property (nonatomic, retain) NSMutableArray *counties; in SearchViewController.m: - (void)getLocationsView { [keywordField resignFirstResponder]; SearchLocationsViewController *locationsController = [[SearchLocationsViewController alloc] initWithNibName:@"SearchLocationsView" bundle:nil]; [self.navigationController pushViewController:locationsController animated:YES]; [locationsController setSelectedCounties:self.counties]; [locationsController release]; } in SearchLocationsViewController.h: @interface EventsSearchLocationsViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { ... NSMutableArray *selectedCounties; } ... @property (nonatomic, retain) NSMutableArray *selectedCounties; in SearchLocationsViewController.m (the point here is, we're toggling each element of a table being active or not in the list of selected counties): -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; if ([self.selectedCounties containsObject:[self.counties objectAtIndex:indexPath.row]]) { //we're deselcting! [self.selectedCounties removeObject:[self.counties objectAtIndex:indexPath.row]]; cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"red_check_inactive.png"]]; } else { [self.selectedCounties addObject:[self.counties objectAtIndex:indexPath.row]]; cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"red_check_active.png"]]; } [tableView deselectRowAtIndexPath:indexPath animated:YES]; } We die at [self.selectedCounties addObject.... there. Now, when I NSLog myself [self.selectedCounties class], it tells me it's an NSCFArray. How does this happen? I understand about class bundles (or I THINK I do anyway), but this is explicitly a specific type, and it's losing it subclassing at some point in a way that kills the whole thing. I just completely don't understand why that would happen.

  • Drawing the UIPicker values from multiple components?

    I have the UIPicker setup with multiple components and a button below it. Depending on what the user has chosen with the UIPicker determines which new view will be loaded but I am having trouble determining how to extrapolate the information from the picker itself. Right now I have this method being called when the button is pressed: - (IBAction) buttonPressed { if (component:1 == 1 && component:2 == 1) { //Load the view number 1. } else if (component:1 == 2 && component:2 == 1) { //Load the view number 2. } else { //Load the view number 3. } } I obviously know that my code is wrong but I hope it gets the point across. I have multiple components and I need to figure out how to use the information that the user is scrolling to on the picker to determine which view to move to. (I know how to load the views, I just commented those in the code to illuminate the problem areas better.)

  • Adding a custom subview (created in a xib) to a view controller's view - What am I doing wrong

    - by Fran
    I've created a view in a xib (with an activity indicator, a progress view and a label). Then I've created .h/.m files: #import <UIKit/UIKit.h> @interface MyCustomView : UIView { IBOutlet UIActivityIndicatorView *actIndicator; IBOutlet UIProgressView *progressBar; IBOutlet UILabel *statusMsg; } @end #import "MyCustomView.h" @implementation MyCustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end In IB, I set the file's owner and view identity to MyCustomView and connect the IBOutlet to the File's owner In MyViewController.m, I've: - (void)viewDidLoad { [super viewDidLoad]; UIView *subView = [[MyCustomView alloc] initWithFrame:myTableView.frame]; [subView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]]; [myTableView addSubview:subView]; [subView release]; } When I run the app, the view is added, but I can't see the label, the progress bar and the activity indicator. What am I doing wrong?

  • 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=?
