AVPlayer not functioning

Question

I'm trying to use an AVPlayer in objective C in a SpriteKit app, but for some reason despite the URL being defined correctly, I can hear no music.

(This is being run from the gameviewcontroller)

-(void)viewDidLoad{
    [super viewDidLoad];
    [self prefersStatusBarHidden]; //hopefully stop an annoying bug.
    NSLog(@"Is it on? %d", _playingMusic);
    if(_playingMusic == 1){ //set audio to play if requested

        NSString *soundPath1 = [[NSBundle mainBundle] pathForResource:@"new_twig_BK2_rehash" ofType:@"mp3"];
        NSURL *soundURL1 = [NSURL fileURLWithPath: soundPath1];
        AVAudioPlayer *BKMPlayer1 = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL1 error:nil];
        BKMPlayer1.numberOfLoops = -1; //infinite loops
        [BKMPlayer1 setVolume: 1.0];
        [BKMPlayer1 stop];
        [BKMPlayer1 setCurrentTime:0];
        [BKMPlayer1 play];
    }


}

Instead of creating the audio player in viewDidLoad method, you should create a strong property of audioPlayer

@property (nonatomic, strong) AVAudioPlayer *BKMPlayer1;

This is because, once the control goes out of the function, the audioPlayer is deallocated by the ARC.
