  var audioPlayer: AVAudioPlayer?

    @IBAction func Creeper(sender: AnyObject) {
        var player = AVPlayer(URL: NSURL(fileURLWithPath: "/Users/abdelrahman/Downloads/Minecraft Creeper Sound sSSSsss BOOM_.mp3"))
        player.play()

    }
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

基本上当你按下按钮时应该播放声音但是当我通过iOS模拟器运行它时，我听不到声音。
