Question

有没有办法在一种方法中拾取所有UIGestureRecognizer事件？（除了通过将所有选择器指向相同的方法）。

例如：

    // Add Gesture Recogniser (Long Press)
    let longPressGR = UILongPressGestureRecognizer(target: self, action: #selector(GcMapView.longPressAction(_:)))
    longPressGR.minimumPressDuration = 1
    self.addGestureRecognizer(longPressGR)

    // Add Gesture Recogniser (Pan)
    let mapDragRecognizer =  UIPanGestureRecognizer(target: self, action: #selector(GcMapView.panAction(_:)))
    mapDragRecognizer.delegate = self
    self.addGestureRecognizer(mapDragRecognizer)

    // Add Gesture Recogniser (Pinch)
    let pinchGestureRecogniser =  UIPanGestureRecognizer(target: self, action: #selector(GcMapView.pinchAction(_:)))
    pinchGestureRecogniser.delegate = self
    self.addGestureRecognizer(pinchGestureRecogniser)    

   // SOME METHOD NOW TO PICKUP ALL EVENTS
   func PICKUPALLEVENTS (sender:UIGestureRecognizer) {
       print("(String(gestureRecognizer.dynamicType) - \(gestureRecognizer.state.hashValue) ")
   }

Answer 1

不，我认为没有办法做到这一点。

Answer 2

您是否尝试向目标添加UIGestureRecognizer，然后检查名为？的选择器中UIGestureRecognizer的动态类型？

在回调中获取所有UIGestureRecognizer事件？
