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

Question

我有一个简单的代码块，可以在点击我的图像时播放声音。但是，当我点击我的图像时，点击甚至都无法识别。

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。

谁能告诉我问题出在哪里？

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!

}

注意UIImageView的userInteractionEnabled默认设置为false。您要将其设置为 true。
