NSMutable Array of sounds plays perfectly until plays 240 sounds

[juanchofern]

Hello i have this problem:

I Create a NSMutable array of 90 sounds.
It plays perfectly, in the device and in the simulator.
But when i play the sounds in the third session i cannot hear the sounds.

Does anybody know why?

Here is the code.


NSMutableArray *sounds;

sounds = [NSMutableArray new];

for (int i=0; i<90;i++
[sounds addObject:[NSString stringWithFormat:@"Juancho%u",i+1]];

NSString *myFile = [sounds objectAtIndexnumber)];
NSString *pathStringAudio = [[NSBundle mainBundle] pathForResource:myFile ofType:@"aif"];
NSURL *pathURLAudio = [NSURL fileURLWithPathathStringAudio];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURLathURLAudio error:&error];

if (audioPlayer == nil)
NSLog([error description]);
else
[audioPlayer play];

Maybe you're running out of memory. 240 AVAudioPlayers at the same time is a bit much. Did you run Instruments on your app to check memory allocation?

Also, where and how is audioPlayer declared? I don't see you releasing the players anywhere. Nor the sounds array for that matter.

You should allocate without keeping a pointer and then sign up for notifications for when the sound is done playing and release there. Or autorelease but I think that might release before the sound is done playing.

I Have declared

AVAudioPlayer *audioPlayer;

in .h

and in .m

in (void) dealloc
[audioPlayer release];

You are overwriting the pointer in each iteration without ever releasing them. You're leaking memory all over the place. Still, 240 players is too much, what exactly are you trying to do?

Hello, i supposed that i was leaking memory, but i don´t know how to release.

How must i do?

i am trying to do a iteration that plays sounds from nsmutable array, and after
when the iteration finalizes, i want to call the function again to play the sounds,
but the problem is that i release the player in the the dealloc.

Do you know how i must do?

Thank you very much for your help.
