iOS，Swift 2.3 - UIPanGesture已启用，但UITapGesture在同一个UIView上禁用

Question

我有一个UIView（蓝色），我想检测它的手势识别器。我想在这个视图上捕捉平移和点按手势，但是当用户点击此视图时，我希望＆＃34;交付＆＃34;此触摸/点按父视图（绿色）。

我的蓝色UIView：

class SwipeView: UIView, UIGestureRecognizerDelegate {

    var tap: UITapGestureRecognizer!
    var pan: UIPanGestureRecognizer!

    func setup() {
        tap = UITapGestureRecognizer(target: self, action: #selector(Swipe.onTap))
        tap.delegate = self
        tap.enabled = true
        self.addGestureRecognizer(tap)

        pan = UIPanGestureRecognizer(target: self, action: #selector(Swipe.onPan))
        pan.delegate = self
        pan.enabled = true
        self.addGestureRecognizer(pan)

        self.backgroundColor = .blueColor()
    }

    func onTap() {
    }

    func onPan() {
    }

    override func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
        return false
    }
}

即使我返回gestureRecognizerShouldBegin = false，绿色UIView也不会捕获任何事件。那么，我该如何在功能上做到这一点？求助。

像这样交付给父母：

func onTap(tapGestureRecognizer: UITapGestureRecognizer) {
    self.superview?.gestureRecognizerShouldBegin?(tapGestureRecognizer)
}
