background music

(using AVFoundation.framework) 

#import "AVFoundation/AVFoundation.h"

So I got a problem, I tried this code first in init method of my class (that is the one that is loaded first)

NSString* soundFilePath = [[NSBundle mainBundle] pathForResource:@"music" ofType:@"mp3"];
NSURL* soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer* player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops=-1;
[player play];

But it didn't work, than I decided to do it in thread: in init method:

[NSThread detachNewThreadSelector:@selector(playMusic) toTarget:self withObject:nil];

and method itself:

-(void) playMusic {
    NSString* soundFilePath = [[NSBundle mainBundle] pathForResource:@"music" ofType:@"mp3"];
    NSURL* soundFileURL = [NSURL fileURLWithPath:soundFilePath];
    AVAudioPlayer* player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
    player.numberOfLoops=-1;
    [player play];
}

it is declared in *.h file of course. It also didn't work.

I tried to debug, on line 

}

of playMusic method the file is played for 2 or 3 seconds and then stops. It isn't played without debug. What is the problem?

The AVAudioPlayer will be deallocated immediately. You need to retain the player. So make the AVAudioPlayer an instance variable of the class.
