  • Ipad SplitViewController navigating to another view

    - by nishantcm
    Hi, I am trying to navigate to a different view in the detailview of the splitviewcontroller. I dont want the new view to display in the split view. I am using this code to change views. This works ok in portrait orientation, but in landscape the split view table view still appears. Can anyone help with this? Next *any = [[Next alloc] initWithNibName:@"Next" bundle:nil]; [self.view addSubview:any.view];

  • XCode sqlite3 - SELECT always return SQLITE_DONE

    - by user573633
    Hi developers.... a noob here asking for help after a day of head-banging.... I am working on an app with sqlite3 database with one database and two tables. I have now come to a step where I want to select from the table with an argument. The code is here: -(NSMutableArray*) getGroupsPeopleWhoseGroupName:(NSString*)gn;{ NSMutableArray *groupedPeopleArray = [[NSMutableArray alloc] init]; const char *sql = "SELECT * FROM Contacts WHERE groupName='?'"; @try { NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES); NSString *docsDir = [paths objectAtIndex:0]; NSString *theDBPath = [docsDir stringByAppendingPathComponent:@"ContactBook.sqlite"]; if (!(sqlite3_open([theDBPath UTF8String], &database) == SQLITE_OK)) { NSLog(@"An error opening database."); } sqlite3_stmt *st; NSLog(@"debug004 - sqlite3_stmt success."); if (sqlite3_prepare_v2(database, sql, -1, &st, NULL) != SQLITE_OK) { NSLog(@"Error, failed to prepare statement."); } //DB is ready for accessing, now start getting all the info. while (sqlite3_step(st) == SQLITE_ROW) { MyContacts * aContact = [[MyContacts alloc] init]; //get contactID from DB. aContact.contactID = sqlite3_column_int(st, 0); if (sqlite3_column_text(st, 1) != NULL) { aContact.firstName = [NSString stringWithUTF8String:(char *) sqlite3_column_text(st, 1)]; } else { aContact.firstName = @""; } // here retrieve other columns data .... //store these info retrieved into the newly created array. [groupedPeopleArray addObject:aContact]; [aContact release]; } if(sqlite3_finalize(st) != SQLITE_OK) { NSLog(@"Failed to finalize data statement."); } if (sqlite3_close(database) != SQLITE_OK) { NSLog(@"Failed to close database."); } } @catch (NSException *e) { NSLog(@"An exception occurred: %@", [e reason]); return nil; } return groupedPeopleArray;} MyContacts is the class where I put up all the record variables. My problem is sqlite3_step(st) always return SQLITE_DONE, so that it i can never get myContacts. (i verified this by checking the return value). What am I doing wrong here? Many thanks in advance!

  • NSOperation inside NSOperationQueue not being executed

    - by Martin Garcia
    I really need help here. I'm desperate at this point. I have NSOperation that when added to the NSOperationQueue is not being triggered. I added some logging to see the NSOperation status and this is the result: Queue operations count = 1 Queue isSuspended = 0 Operation isCancelled? = 0 Operation isConcurrent? = 0 Operation isFinished? = 0 Operation isExecuted? = 0 Operation isReady? = 1 Operation dependencies? = 0 The code is very simple. Nothing special. LoadingConflictEvents_iPad *loadingEvents = [[LoadingConflictEvents_iPad alloc] initWithNibName:@"LoadingConflictEvents_iPad" bundle:[NSBundle mainBundle]]; loadingEvents.modalPresentationStyle = UIModalPresentationFormSheet; loadingEvents.conflictOpDelegate = self; [self presentModalViewController:loadingEvents animated:NO]; [loadingEvents release]; ConflictEventOperation *operation = [[ConflictEventOperation alloc] initWithParameters:wiLr.formNumber pWI_ID:wiLr.wi_id]; [queue addOperation:operation]; NSLog(@"Queue operations count = %d",[queue operationCount]); NSLog(@"Queue isSuspended = %d",[queue isSuspended]); NSLog(@"Operation isCancelled? = %d",[operation isCancelled]); NSLog(@"Operation isConcurrent? = %d",[operation isConcurrent]); NSLog(@"Operation isFinished? = %d",[operation isFinished]); NSLog(@"Operation isExecuted? = %d",[operation isExecuting]); NSLog(@"Operation isReady? = %d",[operation isReady]); NSLog(@"Operation dependencies? = %d",[[operation dependencies] count]); [operation release]; Now my operation do many things on the main method, but the problem is never being called. The main is never executed. The most weird thing (believe me, I'm not crazy .. yet). If I put a break point in any NSLog line or in the creation of the operation the main method will be called and everything will work perfectly. This have been working fine for a long time. I have been making some changes recently and apparently something screw things up. One of those changes was to upgrade the device to iOS 5.1 SDK (iPad). To add something, I have the iPhone (iOS 5.1) version of this application that use the same NSOperation object. The difference is in the UI only, and everything works fine. Any help will be really appreciated. Regards,

  • 3 embedded UIScrollView problem

    - by Infinity
    Hello guys! I have 3 UIScrollView. Here is a sample code, about how they are added in eachother: UIScrollView main; UIScrollView page1; UIScrollView page2; UIScrollView doublePage; UIView pageContent1; UIView pageContent2; UIView doublePageContent; int nrPages = 1; sw2 = 0; main = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0, 0.0, 768, 980)]; main.contentSize = CGSizeMake(768 * (nrPages - 1 + sw2), 980); page1.frame = CGRectMake(0, 0, 768, 980); page2.frame = CGRectMake(768, 0, 768, 980); pageNumber = i - 1 + sw2; (i is a variable in a for loop) doublePage.frame = CGRectMake(768 * (pageNumber - 1), 0, 768 * 2, 980); CGFloat contentWidth = [page1 bounds].size.width + [page2 bounds].size.width; CGFloat contentHeight = page1 ? self.page1.bounds.size.height : self.page2.bounds.size.height; doublePageContent = [[UIView alloc] initWithFrame:CGRectMake(0, 0, contentWidth, contentHeight)]; [page1 addSubview:pageContent1]; [page2 addSubview:pageContent2]; [doublePageContent addSubview:page1]; [doublePageContent addSubview:page2]; [doublePage addSubview:doublePageContent]; [main addSubview:doublepage]; And with this structure the main scrollview don't want to scroll. Without the doublepage scrollview it is working good. What do you think? What's the problem? I know this structure is a little weird, but I need this structure because other parts of the code. Edited, added the information about the sizes. If you need something more please tell me. And one more thing.. If I add 1 pixel to the width of the doublePage contentSize.width it scrolls, but a bit hard, so it scrolls first in the doublePage and then in the main.

  • How to create a specific date in the distant past, the BC era.

    - by alloy
    I’m trying to create a date in the BC era, but failing pretty hard. The following returns ‘4713’ as the year, instead of ‘-4712’: NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [NSDateComponents new]; [components setYear: -4712]; NSDate *date = [calendar dateFromComponents:components]; NSLog(@"%d", [[calendar components:NSYearCalendarUnit fromDate: date] year]); Any idea what I’m doing wrong?

  • Best point to overwrite the navigationBar property of navigationController

    - by flohei
    Hi there, I'm overwriting UINavigationController to replace the default navigationBar property with an instance of my own subclass of UINavigationBar. So I tried something like _navigationBar = [[SBNavigationBar alloc] init]; in my -initWithRootViewController:. But that didn't work out as I expected it. There's still the default navigationBar being displayed. So what's the best point to overwrite the navigationBar? Thanks in advance –f

  • How to send a array as a parameter to a web service using SOAP and objective C.

    - by Alejandra Meraz
    I'm working in a iPhone app that needs to send a array as a parameter using SOAP. this is the current request and connection: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body>\n" "<function xmlns=\"http://tempuri.org/\" />\n" "</soap:Body>\n" "</soap:Envelope>\n"]; NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]]; [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"]; [theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"]; [theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; Now, to send parameters I looked at the WSDL of the function description for the input is like this: <s:complexType name="ArrayOfDictionaryEntry"> <s:sequence> <s:element minOccurs="0" maxOccurs="unbounded" name="DictionaryEntry" type="tns:DictionaryEntry" /> </s:sequence> </s:complexType> <s:complexType name="DictionaryEntry"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Key" /> <s:element minOccurs="0" maxOccurs="1" name="Value" /> </s:sequence> </s:complexType> <s:element name="functionInput"> <s:complexType /> </s:element> I guess then that I need to make a array of dictionary entries. what I would like to send is something like this [ location => USA, module => DEVELOPMENT] But I'm kind of confused. the array is created outside the SOAP, like an NSArray or inside the SoapMessage? if so... How is it done? and the DictionaryEntry, should I make a class? thanks for your time n.n

  • Can lazy loading be considered an example of RAII?

    - by codemonkey
    I have been catching up on my c++ lately, after a couple years of exclusive Objective-C on iOS, and the topic that comes up most on 'new style' c++ is RAII To make sure I understand RAII concept correctly, would you consider Objective-C lazy loading property accessors a type of RAII? For example, check the following access method - (NSArray *)items { if(_items==nil) { _items=[[NSArray alloc] initWithCapacity:10]; } return _items } Would this be considered an example of RAII? If not, can you please explain where I'm mistaken?

  • Cocoa class not displaying data in NSWindow

    - by Matt S.
    I have one class that controls one window, and another class that controls a different window in the same xib, however, the second window never displays what it should. In the first class I alloc and init the second class, then pass some information to it. In the second class it displays that data in the table view. Yes, in the .xib I have all the connections set up correctly, I've quadruple checked. Also the code is correct, same with the connections, I've quadruple checked.

  • How can I get a file's size in C?

    - by Nino
    How can I find out the size of a file? I opened with an application written in C. I would like to know the size, because I want to put the content of the loaded file into a string, which I alloc using malloc(). Just writing malloc(10000*sizeof(char)); is IMHO a bad idea.

  • Storing an subtitle on an annotation with NSUserDefualts

    Hey everybody! Basically: what i try to do is to save the street address of an annotation so that when I quit the application and launch it again the street address still will be there...see the following code: SavePosition.m -(NSString *)subtitle{ if (!subtitle) { return @"Ingen gata i närheten"; } else { return subtitle; } } -(NSString *)title{ return @"Sparad Position"; } -(id)initWithCoordinate:(CLLocationCoordinate2D) coor{ self.coordinate=coor; NSLog(@"%f,%f",coor.latitude,coor.longitude); return self; } - (void)setCoordinate:(CLLocationCoordinate2D)koor { MKReverseGeocoder *geocoder = [[[MKReverseGeocoder alloc] initWithCoordinate:koor] autorelease]; geocoder.delegate = self; coordinate = koor; [geocoder start]; } - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error { NSLog(@"fail %@", error); } - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark { self.subtitle = [placemark.addressDictionary valueForKey:@"Street"]; } -(void)applicationWillTerminate:(UIApplication *)application { NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults]; [userDef setValue:subtitle forKey:@"SavedAddress"]; [userDef setBool:YES forKey:@"Street"]; [userDef synchronize]; } @end mainViewController.m -(void)viewDidLoad { [super viewDidLoad]; NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults]; if ([userDef boolForKey:@"sparadKoordinat-existerar"]) { CLLocationCoordinate2D savedCoordinate; savedCoordinate.latitude = [userDef doubleForKey:@"sparadKoordinat-latitud"]; savedCoordinate.longitude = [userDef doubleForKey:@"sparadKoordinat-longitud"]; SparaPosition *position=[[SparaPosition alloc] initWithCoordinate:savedCoordinate]; [mapView addAnnotation:position]; savedPosition = savedCoordinate; raderaSparad.enabled=YES; skickaMaps.enabled=YES; mStoreLocationButton.enabled=NO; friZoom = NO; NSString *savedAddress = [[NSUserDefaults standardUserDefaults] objectForKey:@"SavedAddress"]; if (savedAddress) { savedAddress.subtitle = [userDef valueForKey:@"Street"]; // what code should I add here? } MKCoordinateRegion region; region.center.latitude = savedCoordinate.latitude; region.center.longitude= savedCoordinate.longitude; MKCoordinateSpan span; span.latitudeDelta = 0.01; span.longitudeDelta = 0.01; region.span = span; region = [mapView regionThatFits:region]; [mapView setRegion:region animated:YES]; [mapView setRegion:region animated:TRUE]; }

  • How to update NSMutableDictionary. My code doesn't work.

    - by dawatson833
    I've populated an array using. arrSettings = [[NSMutableArray alloc] initWithContentsOfFile:[self settingsPath]]; The file is a plist with the root as an array and then a dictionary with three three keys defined as number. I've also tried setting the keys to string. I display the values in the plist file on a view using. diaper = [[arrSettings objectAtIndex:0] objectForKey:@"Diaper Expenses"]; oil = [[arrSettings objectAtIndex:0] objectForKey:@"Oil Used"]; tree = [[arrSettings objectAtIndex:0] objectForKey:@"Wood Used"]; This code works fine, the values in the dictionary are assigned to the variables and they are displayed. The user can make changes and then press a save button. I use this code to extract the dictionary part of the array so I can update it. The assignment to editDictionary works. I've double checked the key names including case and that is correct. editDictionary = [[NSMutableDictionary alloc] init]; editDictionary = [arrSettings objectAtIndex:0]; NSNumber *myNumber = [NSNumber numberWithFloat:diaperAmount]; [editDictionary setValue:myNumber forKey:@"Diaper Expenses"]; myNumber = [NSNumber numberWithFloat:oilAmount]; [editDictionary setValue:myNumber forKey:@"Oil Used"]; myNumber = [NSNumber numberWithFloat:treeAmount]; [editDictionary setValue:myNumber forKey:@"Wood Used"]; In this example I've used a nsnumber. But I've also tried the xxxAmount field as part of SetValue instead of creating a NSNumber. Neither implementation works. Several strange things happen. Sometimes the first two setvalue statements work, but the last setvalue fails with a EXC_BAD_ACCESS failure. Other times the first setValue fails with the same error. I have no idea why the first two sometimes work. I'm at a loss of what to do next. I've tried several implentations and none of them work. Also, in the debugger how can I display the editDictionary elements. I can see editDictionary, but I don't know how to display the individual elements.

  • Simple calculator app crashes when a third number key is punched.

    - by Justin
    Hi , I am a newbie to the iphone app world. So I thought I try my luck with a calculator app. Unfortunately I am running into an issue where if I press a third key in the calculator the app crashes. Sometimes I get this error EXC_BAD_ACCESS. Here is a code in my CalculatorViewController.m file. #import "CalculatorViewController.h" @implementation CalculatorViewController @synthesize screenText; - (IBAction)buttonPressed:(id)sender { NSString *title = [sender titleForState:UIControlStateNormal]; [self collect:title]; } - (void)collect:(NSString *)digitz { NSString * newText = nil; if ([digitz isEqualToString:@"+"]) { [self add:result]; big_digit = nil; } else if ([digitz isEqualToString:@"+"]) { [self sub:result]; } else if ([digitz isEqualToString:@"x"]) { [self multiply:result]; } else if ([digitz isEqualToString:@"="]) { [self equate:result]; } else { if (big_digit != nil && [big_digit isEqualToString:@"0"] == FALSE) big_digit = [big_digit stringByAppendingFormat:@"%@",digitz]; else big_digit = (NSMutableString *) digitz; result = (int) big_digit; newText = [[NSString alloc] initWithFormat: @"%@",big_digit]; } screenText.text = newText; [newText release]; } - (void)add:(int)res { NSString * newText = nil; ans = ans + res; newText = [[NSString alloc] initWithFormat: @"%@",ans]; screenText.text = newText; [newText release]; } Can anyone spot an obvious issue here. Here is the respective header file too. #import <UIKit/UIKit.h> @interface CalculatorViewController : UIViewController { UILabel *screenText; int number; int result; int ans; //NSString *big_digit; NSMutableString * big_digit ; } @property (nonatomic, retain) IBOutlet UILabel *screenText; - (IBAction)buttonPressed:(id)sender; - (void)collect:(NSString *)digitz; - (void)add:(int)num; - (void)sub:(int)num; - (void)multiply:(int)num; - (void)equate:(int)num; @end
