AudioToolBox leak in iOS6?

Question

When I use AudioToolBox for playing music, memory leaks heavily.

AVAudioPlayer *newMusicPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error];
         


        

Answer 1

Maybe you did better than me and I haven't the XCode in my front, but :

object created, reference created:

AVAudioPlayer *newMusicPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error];

it is assignment and not allocation, no retain:

_musicPlayer = newMusicPlayer;

out of function playMusicWithMusicData it would deallocate the newMusicPlayer and it would crash my code in other function when I use the _musicPlayer. The analyzer tool nagged so much as I made a retain, maybe a release too.

if you are using ios4, than isn't ARC this project.

in if branch:

    [_musicPlayer stop];
    _musicPlayer = nil;

I would check the _musicPlayer to not be nil, but that will not solve your problems.

No clue where it could be, if not in ios and probably there it will be:

Did solve if you change the delegate instead of self.

 _musicPlayer.delegate = self;

to any other class?
