Does it play in the simulator? Can you share the code?

Yep, plays in simulator. Here is some of the code, just followed what the lesson said:

  • (void)viewDidLoad { [super viewDidLoad];

    NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"crystal_ball" ofType:@"mp3"]; NSURL *soundURL = [NSURL fileURLWithPath:soundPath]; AudioServicesCreateSystemSoundID(CFBridgingRetain(soundURL), &soundEffect);

    //then..

pragma mark - Prediction

  • (void) makePrediction { [self.backgroundImageView startAnimating]; self.predictionLabel.text = [self.crystalBall randomPrediction]; AudioServicesPlaySystemSound(soundEffect); [UIView animateWithDuration:5.0 animations:^{ self.predictionLabel.alpha = 1.0f; }];

}

Thanks!

I figured it out. I copy pasted your code into my Crystal Ball project to make sure it was all the same and it is. So I put it on my device and it didn't work. So I searched and found that there is a second audio control in the settings app under sounds. Turn that up and it should work. It worked for me. Stack Overflow
