I'm facing several crashes when developing a game, probably due to some sort of sound management bugs. This is what my trace says about them:
Thread : Crashed: com.apple.main-thread
0 libobjc.A.dylib 0x000000019599bbd0 objc_msgSend + 16
1 CoreFoundation 0x00000001851d4ae4 __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ + 20
2 CoreFoundation 0x0000000185113220 _CFXNotificationPost + 2060
3 AVFoundation 0x0000000183a4af8c __avplayeritem_fpItemNotificationCallback_block_invoke + 5336
4 libdispatch.dylib 0x0000000195fcd3ac _dispatch_call_block_and_release + 24
5 libdispatch.dylib 0x0000000195fcd36c _dispatch_client_callout + 16
...
The line #3 is about AVFoundation and a AVPlayerItem so I guess I have something wrong with my music AVPlayerItems objects, but what... ? :)
Any advice is much appreciated!
Add this code in your ViewController
-(void) viewWillDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
[super viewWillDisappear:animated];
}
And add this observer again in viewWillAppear method.
