  • Retrieving NSDate from NSString

    - by Olivier de Jonge
    I have an iPhone app. that is receiving data with IRFC 3339 timestamp format (e.g. @"2010-01-29T11:30:00.000+01:00"), as in GData. I want to convert the data to an NSDate NSDateFormatter *inputFormatter = [[[NSDateFormatter alloc] init] autorelease]; [inputFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS"]; [currentEntry setStartTime:[inputFormatter dateFromString: ][currentEntry startTimeString]]]; But I'm missing out how to convert the last part of the string @"2010-01-29T11:30:00.000+01:00": the time offset. Anyone knows what I have to add to this String to take the time offset in account too?

    - by Cesar
    I need to wait (don't execute the code) after the presentModalViewController until the modal view it's dismissed, it's possible or it's a conceptual error ? -(NSDictionary *)authRequired { [self presentModalViewController:loginRegView animated:YES]; //This view write the settings when dismissed. NSMutableDictionary *ret=[[NSMutableDictionary alloc] init]; [ret setObject:[app.settings get:@"user"] forKey:@"user"]; [ret setObject:[app.settings get:@"pass"] forKey:@"pass"]; return ret; }

  • Weird background offset of UIToolbar when in formSheet.

    - by Mike A
    As you can see in the pic, the buttons from the toolbar on the right align perfectly with the segmented control on the left. They are displayed on the navigation bar. For some reason though, the background of the toolbar seems to be offset 1px to the bottom. What is especially weird, is this exact same view controller, in fullScreen or even pageSheet, displays everything properly. Segmented control is being allocated: UISegmentedControl* segmentControl = [[UISegmentedControl alloc] initWithFrame:CGRectMake(0,0,300,30)]; Toolbar is being allocated: UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100,44)]; I've spent hours trying to fix this, it's driving me crazy.

  • setContentOffset only works if animated is set to YES

    - by Sheehan Alam
    I have a UITableView which I would like to be displayed 100px down. For some reason this only works when animated is set to YES. Why is this? - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; /*[self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0] atScrollPosition:UITableViewScrollPositionNone animated:NO];*/ /*[self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathWithIndex:1] atScrollPosition:UITableViewScrollPositionNone animated:NO];*/ [self.tableView setContentOffset:CGPointMake(0,100) animated:YES]; }

  • Plist won't copy to documents directory

    - by John
    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. Error %@", [error localizedDescription]); } I am given the error " * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to copy Plist. Error Operation could not be completed. No such file or directory'" in the console however. Any idea what is wrong? Thanks

  • Help creating custom iPhone Classes

    - by seanny94
    This should be a simple question, but I just can't seem to figure it out. I'm trying to create my own class which will provide a simpler way of playing short sounds using the AudioToolbox framework as provided by Apple. When I import these files into my project and attempt to utilize them, they just don't seem to work. I was hoping someone would shed some light on what I may be doing wrong here. simplesound.h #import <Foundation/Foundation.h> @interface simplesound : NSObject { IBOutlet UILabel *statusLabel; } @property(nonatomic, retain) UILabel *statusLabel; - (void)playSimple:(NSString *)url; @end simplesound.m #import "simplesound.h" @implementation simplesound @synthesize statusLabel; - (void)playSimple:(NSString *)url { if (url = @"vibrate") { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); statusLabel.text = @"VIBRATED!"; } else { NSString *paths = [[NSBundle mainBundle] resourcePath]; NSString *audioF1ile = [paths stringByAppendingPathComponent:url]; NSURL *audioURL = [NSURL fileURLWithPath:audioFile isDirectory:NO]; SystemSoundID mySSID; OSStatus error = AudioServicesCreateSystemSoundID ((CFURLRef)audioURL,&mySSID); AudioServicesAddSystemSoundCompletion(mySSID,NULL,NULL,simpleSoundDone,NULL); if (error) { statusLabel.text = [NSString stringWithFormat:@"Error: %d",error]; } else { AudioServicesPlaySystemSound(mySSID); } } static void simpleSoundDone (SystemSoundID mySSID, void *args) { AudioServicesDisposeSystemSoundID (mySSID); } } - (void)dealloc { [url release]; } @end Does anyone see what I'm trying to accomplish here? Does anyone know how to remedy this code that is supposedly wrong?

  • AVAudioPlayer not unloading cached memory after each new allocation

    - by Rob
    I am seeing in Instruments that when I play a sound via the standard "AddMusic" example method that Apple provides, it allocates 32kb of memory via the prepareToPlay call (which references the AudioToolBox framework's Cache_DataSource::ReadBytes function) each time a new player is allocated (i.e. each time a different sound is played). However, that cached data never gets released. This obviously poses a huge problem if it doesn't get released and you have a lot of sound files to play, since it tends to keep allocating memory and eventually crashes if you have enough unique sound files (which I unfortunately do). Have any of you run across this or what am I doing wrong in my code? I've had this issue for a while now and it's really bugging me since my code is verbatim of what Apple's is (I think). How I call the function: - (void)playOnce:(NSString *)aSound { // Gets the file system path to the sound to play. NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:aSound ofType:@"caf"]; // Converts the sound's file path to an NSURL object NSURL *soundURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; self.soundFileURL = soundURL; [soundURL release]; AVAudioPlayer * newAudio=[[AVAudioPlayer alloc] initWithContentsOfURL: soundFileURL error:nil]; self.theAudio = newAudio; // automatically retain audio and dealloc old file if new m4a file is loaded [newAudio release]; // release the audio safely // this is where the prior cached data never gets released [theAudio prepareToPlay]; // set it up and play [theAudio setNumberOfLoops:0]; [theAudio setVolume: volumeLevel]; [theAudio setDelegate: self]; [theAudio play]; } and then theAudio gets released in the dealloc method of course.

  • Getting x/y coordinate of a UITouch...

    - by Tarek
    HI, I have been trying to get the x/y coordinates from a touch on any iDevice. When getting the touch locations, everything looks ok if the touch is in the middle of the screen. But if I drag my finger to the bottom of the screen, I can only get a y coordinate of 1015. It should be getting to 1023. Same thing for dragging my finger to the top of the screen. I get -6. It should be 0. I have explicitly set the window and views to an origin of 0,0 and the width, height of the device's screen. Still nothing. I am really lost on what might be going on. Is something shifted? Am I not reading the x/y coordinates properly. Does something need to be transformed or converted? Any help would be much appreciated. T

  • Prevent automatic popToRootViewController on double-tap of UITabBarController

    - by NilObject
    The default behavior of a UITabBarController is to pop the contained UINavigationController to the root view controller when a particular tab is tapped a second time. I have a particular use case where I'm wanting this to not work automatically, and I'm having a hard time figuring out how to prevent this. Has anyone run into this, and if so, what did you do? Do I need to subclass UINavigationController and override popToRootViewController or is there a simpler way?
