自身のviewはタッチに反応させず親viewに任せるが子viewのタッチは反応させる

Last updated at Posted at 2017-06-22

isUserInteractionEnabled=falseだと子viewのタッチも反応しないから困るよねってやつ
古典的なやり方なせいかSwift版が見つからなかったんでメモ

  //UIViewのサブクラスでこのメソッドをオーバーライド
  override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
    let view = super.hitTest(point, with: event)
    return view == self ? nil : view
  }
