iOS/Swift UIImageView(.jpg)无法识别我的点按手势？

Question

当我的图像被点击时,我有一个简单的代码块来播放声音.但是,当我点按图像时,甚至无法识别水龙头.

我相信这是真的,因为handleTap函数中的println在点击图像时不会打印任何内容.

谁能给我一些关于问题可能在哪里的见解？

var coinSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("wavSampleSound", ofType: "wav")!)
var audioPlayer = AVAudioPlayer()

override func viewDidLoad() {
    super.viewDidLoad()

    loadSound()

    let gesture = UITapGestureRecognizer(target: self, action: "handleTap:")
    gesture.delegate = self
    myImage.addGestureRecognizer(gesture)
}
func loadSound() {
    audioPlayer = AVAudioPlayer(contentsOfURL: coinSound, error: nil)
    audioPlayer.prepareToPlay()

}
func handleTap(gesture: UITapGestureRecognizer) {
    let playsSound = self.audioPlayer.play()
    println("\(playsSound)")
}


@IBOutlet weak var myImage: UIImageView!

}

请注意,默认设置userInteractionEnabled的UIImageView是false.你想把它设置为true.
