Swift，UILongPressGestureRecognizer在UIlabel中不起作用

Question

I am trying long press Gesture in Swift for Copy Option.

But it is not working. It is not identifying the Gesture in UiView Or UILabel either.

Below is my Code

In View DidLoad

     let copyLongPress = UILongPressGestureRecognizer(target: self, action: #selector(ContactDetailController.handleLongPress(_:)))
    copyLongPress.numberOfTouchesRequired = 0
    copyLongPress.delegate = self
    copyLongPress.minimumPressDuration=0.5
    self.lblDynaMobile.addGestureRecognizer(copyLongPress)
    self.lblDynaMobile.userInteractionEnabled = true
    self.lblDynaDDI.addGestureRecognizer(copyLongPress)
     self.lblDynaDDI.userInteractionEnabled = true
    self.GeneralView.addGestureRecognizer(copyLongPress)
    self.EmailView.addGestureRecognizer(copyLongPress)
    self.AddressView.addGestureRecognizer(copyLongPress) 

New Mothod

func handleLongPress(longPressView :UILongPressGestureRecognizer) {

    let lblFont:UILabel = (longPressView.view as? UILabel)!
    UIPasteboard.generalPasteboard().string = lblFont.text

}

I have added UIGestureRecognizerDelegate too in the Declaration of class

Try this, and see (it's working.)

// in viewDidLoad()
let copyLongPress = UILongPressGestureRecognizer(target: self, action: #selector(self.handleLongPress(_:)))
self.lblDynaMobile.addGestureRecognizer(copyLongPress)

func handleLongPress(_ gesture: UILongPressGestureRecognizer) {

    if let lblFont = gesture.view as? UILabel {
      //UIPasteboard.generalPasteboard().string = lblFont.text
    }

}
