UILongPressGestureRecognizer 接受灵活数量的触摸

Question

我有一个 UILongPressGestureRecognizer，它会在屏幕上有一根手指时触发。但是，一旦我放了 2 个手指，该功能就不再被触发，我需要为 2 个手指创建一个新的手势。如何让 UILongPressGestureRecognizer 接受灵活数量的触摸？

let longScreenGesture = UILongPressGestureRecognizer(target: self, action: #selector(screenTapped(_:)))
longScreenGesture.minimumPressDuration=0.1
longScreenGesture.allowableMovement=0
longScreenGesture.numberOfTouchesRequired=1
sceneView.isMultipleTouchEnabled=true
sceneView.addGestureRecognizer(longScreenGesture)

@objc func screenTapped(_ sender: UILongPressGestureRecognizer)
{
        print(sender.numberOfTouches) // -> Always displays 1
}

Answer 1

我最终使用了 TouchesBegan / Moved / Ended 并自己分析了手势
