view的响应事件传递 在superView里面用 hitTest(_ point: CGPoint, with event: UIEvent?） 方法，找出事件响应区域内的point 传递给subVIew即可
public override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
var view = super.hitTest(point, with: event)
if view == nil {
for subView in self.subviews {
let tp = subView.convert(point, from: self)
if subView.bounds.contains(tp) {
view = subView
}
}
}
return view
}
