However… I am also experiencing a memory leak using AVAudioPlayer. Thanks to Instruments/Leaks and this blog, every other memory leak in my program has been tracked down and quashed, but not this one. With this bit of code:

NSURL *backgroundMusicURL = [ NSURL fileURLWithPath: [ [ NSBundle mainBundle ] pathForResource: @"test" ofType: @"mp3" ] ];
self.backgroundMusic = [ [ AVAudioPlayer alloc ] initWithContentsOfURL: backgroundMusicURL error: NULL ];
[ self.backgroundMusic release ];

self.backgroundMusic.volume = 0.5; self.backgroundMusic.delegate = self; [ self.backgroundMusic prepareToPlay ];

I get a memory leak on the prepareToPlay line. If I remove that line, then I don’t get a memory leak flagged until some time later, when I call [ self.backgroundMusic play].

I use AVAudioPlayer elsewhere to play non-MP3 using basically exactly the same code, with no memory leaks.

Any ideas?

Thanks,

Dingo

• (void)applicationDidFinishLaunching:(UIApplication *)application {

  [window makeKeyAndVisible];

  NSString *file = [[NSBundle mainBundle] pathForResource:@”paris” ofType:@”mp3″]; NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: file];

  AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil]; [fileURL release]; self.player = newPlayer; [newPlayer release]; [self.player play]; }

• (void)dealloc { [window release]; [super dealloc]; [player release]; }

Also, my colours are different too. Cyan blocks just show hex numbers (a library without debug info available?), while blocks matching the app appear green. Sorry, but being a heterosexual male, cyan/green is as much distinction as I can make between colours :)

However the leak in applicationDidFinishLaunching is not recorded by Instruments.

Does it detect them when you click the “Leak” button? Are you sure you’re waiting for it to timeout or clicking the “Check For Leaks Now” button? It doesn’t display leaks in real-time. It checks for new leaks every 30 seconds.

I was unable to get instruments to detect the leak in the applicationDidFinishLaunching method. Am i doing something wrong or does it not pick it up.

Send me a screenshot at matt at cimgf dot com so I can take a look.
