You should use the AVFoundation framework. You can use the AVAudioPlayer class like this:

NSString * fPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"audiofile.mp3"];
NSURL * url = [NSURL fileURLWithPath:fPath];
AVAudioPlayer * audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url
                                                                     error:nil];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
