如何设置UIView来检测触摸（不是点击）

Question

I am trying to make my interface feel more responsive. A UIView changes color on user touch and I want it to do so already when the View is touched. I could implement a UITapGestureRecognizer but a tap is not what I am looking for, since it requires the touch to end before being recognized.

I imagine this to be quite simple. Or am I wrong?

Do I create a custom UIGestureRecognizer class?

Answer 1

Have you tried touchedBegan ?

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
  if let touch = touches.first {
    // ...
  }
  super.touchesBegan(touches, with: event)
}
