so I have the code shown but my music is not playing and I'm not sure why. the sound on my computer is turned up xcode can play the file that i imported in.

-(void)viewWillLayoutSubviews
{
    [super viewWillLayoutSubviews];
    NSError *error;
    NSLog(@"starting Music");
    NSURL * backgroundMusicURL = [[NSBundle mainBundle] URLForResource:@"rainbowRoad" withExtension:@"m4a"];
    self.backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:&error];
    self.backgroundMusicPlayer.numberOfLoops = -1;
    [self.backgroundMusicPlayer prepareToPlay];
    [self.backgroundMusicPlayer play];
    NSLog(@"awesome");
}
役に立ちましたか?

I don't think your sound file is being copied. Select your audio file in Xcode, then in the File Inspector's Target Membership section, make sure your target is checked.

Check this thing!
