Question

In my app I use AVAudioPlayer to play some mp3. My code is:

- (void) play{
    NSString *path = [NSString stringWithFormat:@"%@/%@",
                      [[NSBundle mainBundle] resourcePath],
                      [arraysound objectAtIndex:appDelegate.indexSound]];
    NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO];
    soundID = [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
    soundID.delegate = self;
    [soundID prepareToPlay]; 
    [soundID play];  
}

but I have 40 sounds to play; I use everytime soundID to play my sounds

example I have sound1.mp3, sound2.mp3, sound3.mp3……

How can I release my soundId?

When my sound change I call “play” method but this method alloc a new AVAudioPlayer everytime

I Know

- (void) audioPlayerDidFinishPlaying: (AVAudioPlayer *) player
                    successfully: (BOOL) flag {

but I don’t understand how to release my sound id inside this delegate method, because if I release inside soundId my app crash
after some minutes that I use my app I have with crash this message “shm_open failed: “Apple Audio Queue”

please help me…thanks

You don’t want to release soundID in your delegate method. You want to release player. Judging from your code, soundID is an ivar. When the delegate gets called, soundID may have been set to another value. But the player parameter will be the AVAudioPlayer that has just finished playing.
