basically Im making a game on Sprite Kit using Obj-C in XCode 5
whenever I tap the screen, I use an SKAction to play a sound file
[self runAction:[SKAction playSoundFileNamed:#"tap.caf" waitForCompletion:NO]];
Previously I used the mp3 file that i had of the same sound and the error kept popping up randomly after about more than 50 taps at least, sometimes more sometimes less, sometimes it doesn't even cause an error,
So i read the apple documentation and decided to convert to ima4 .caf extention.
I'm not sure if its made a difference, It happens much less often. I've got 2 more audio files that are played through SKActions and none of them have yet failed loading.
Any suggestions?
Debug console output below:

Just to add, I tried to check if the file was faulty by setting a repeatforever waitforcomplete:YES SKAction playing the sound file, (i did wait for it to complete each time otherwise, it may have crashed due to significant number of actions). It ran without problem for at least 5 mins, until i decided to stop the app. Not sure if this confirms the file is not damaged
EDIT 2 : Just tried a different sound file and it happened again with a different file :(
I have no explanation about why that "crash" occurs,
but, you can easily solve this problem by declaring and loading your sounds into cash (to avoid to load it each time the sound is played) as follow:
In the .h
#property (strong, nonatomic) SKAction *aSound;
in the .m
Ignit it on the top:
self.aSound = [SKAction playSoundFileNamed:#"FileName.wav" waitForCompletion:NO];
En then call it each time you want to play the sound:
[self runAction:_aSound];
Also and for some reasons,
I advice you to convert all your Audios files into .Wav, which is uncompressed (allowing much more speed from the Processor that hasn't uncompressed the file before to read it)
It also dodge a lot of exceptions in C picked-up from the Breakpoint of Xcode.

I am trying to play a movie using MPMoviePlayerController. When I call play method, i am getting following crash.
*** Terminating app due to uncaught exception 'NSRangeException', reason: 'Cannot remove an observer <MPAVController 0x15786750> for the key path "currentItem" from <MPAVPlaylistManager 0x15787750> because it is not registered as an observer.'

I am not sure whats happening, as I dont have setup any KVO observer for currentItem from MPAVPlaylistManager which is an internal class.
anybody else got this issue?
Your app is massing with MPMoviePlayerController instance that was created. I had the same issue a while back and As far as i can think of there can be two things 1. You are changing contentURL of the instance that you have created while playing a video 2.you are incorrectly releasing the instance of MPMoviePlayerController.
I resolved the issue, the problem was related to iOS7 (that is under NDA at the moment). AVPlayer behaviour is changed if the player is started from a secondary thread. the player object will be nil. fixed my issue.
Can i reuse an existing GPUImageMovieWriter (after calling finishRecording) or is there a method to pause and resume the recording?
I get error if i call startRecoding after a finishRecording.
Terminating app due to uncaught exception 'NSInternalInconsistencyException',
reason: '*** -[AVAssetWriter addInput:] Cannot call method when status is 2'
You can't call startRecording() on the same movieWriter instance after calling finishRecording().
finishRecording() writes the completion block for the video into file, thus all subsequent frames added to the video file would be useless anyway. If what you want to achieve is to pause recording for a bit and append video at the end again after pausing, you should probably create a "pause" state where you don't record, but simply measure the amount of time paused, and then use an adjusted frame time for when you resume recording again.

I can't quiet figure how to debug this. I have a CCScene running and when the scene is replaced I get the following error message.
The scene has a sprite batch node where the CCSpriteSubclass is added.
That's the cleanup method and below that you will find the assertion failure message:
-(void) cleanup
{
[[GameController sharedGameController].musicLayer removeMusicSourceForKey:backgroundMusicFileName];
[CCTextureCache purgeSharedTextureCache];
[CCSpriteFrameCache purgeSharedSpriteFrameCache];
[CCAnimationCache purgeSharedAnimationCache];
// [[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames];
[super cleanup];
}
The batch node is created as following in the initWithId:(int)sceneId method:
//Prepare sprites sheets for the rest of the game art
[frameCache addSpriteFramesWithFile:[NSString stringWithFormat:#"art%i-hd.plist", sceneId]];
sharedSpriteMainBatchNode = [CCSpriteBatchNode batchNodeWithFile:[NSString stringWithFormat:#"art%i-hd.png", sceneId]];
And then I add all CCSpriteSubclass objects.
That's the assertion failure message:
** Assertion failure in -[CCSpriteSubclass setTexture:], /Users/xxx/Desktop/xxx/xxx/libs/cocos2d/CCSprite.m:934

EDIT: Added a breakpoint to the setTexture method and here is what I "DON't" see :)
EDIT 2: I whish I could manage to retrieve the full stacktrace like in Java.. I have asked this in a different question and I was told I should add a global exception.. I still need to figure out how to retrieve the stacktrace..
From the text of your exception message it seems that you create sprites with spriteframes from different spritesheets.
I solved this problem in the same way as here. It was due to the fact that sprite frames where referred while the previous class was replacing the existing one and hence the previous class cleanup method was calling the purge frame cache which was consequently removing the yet unused sprite frames which where being loaded in memory by the newly created object.
I am using Prime31's GameCenter Turn Based plugin in my game in order to handle online matches. A problem arises when I receive an "invitation to play" notification from Game Center while Game Center's matchmaker is showing (called using the plug-in => GameCenterTurnBasedBinding.findMatch(2,2,false); ).
The app crashes and the following output is shown in Xcode:

I have tried disabling notifications through the Ipad/Iphone settings for both my app and GameCenter as well as through the code by removing all notification related code but this hasn't had any effect at all.
I know through debugging that the code in my function attached to GameCenterTurnBasedManager.handleTurnEventEvent doesn't get called before the crash occurs, and neither does the one registered to EtceteraManager.remoteNotificationReceived. (Both these function work perfectly fine otherwise.)
I have asked Prime31 and they have told me that the exception is a mishandling of the tables data source, and to file a bug report with Apple.
Has anyone experienced a similar crash/error while working with Unity?
And is there any way I can try to catch the notification before it arrives and remove the matchmaker or be able to handle the error from unity?
Any insight/help/comments would be greatly appreciated,
Thanks.
After upgrading to XCode4 (v. 4.2, 4D199) it seems every time my apps crash while debugging, the debugging points to main(), and the stack is unsymbolicated and useless.
This has been working fine for years, I have no idea what has gone wrong.
I'm using GDB. I also tried the LLDB as per this advice, and it didn't work either (similar, useless stack).
My breakpoints work, I get the full stack, and can inspect variables when my code hits those.
Steps to reproduce:
NB. this happens with my own project, but I'll use Apple's code here to remove that variable from the equation
Download the following sample from Apple: https://developer.apple.com/library/ios/#samplecode/UICatalog/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007710
In the ImagesViewController class, add the following code to the viewDidLoad method (so it will crash – we want it to crash for this test):
// please note: this code is designed to crash! I want it to crash, to highlight my issue with XCode.
NSMutableArray* test = [NSMutableArray new];
[test insertObject:NULL atIndex:0];
Then run the app & hit the 'Images' row.
It crashes with a message like:
2011-12-23 14:07:02.788 UICatalog[13394:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

Thanks to brigadir for pointing me to the solution!
It works well. Here's some screenshots for how to solve this for anyone finding my question:
Tap the plus button of the breakpoints tab
Then click Done
