Swift 3 TapGestureRecognizer 选择器抛出错误

Question

我已经查看了其他几个 post 问题，将目标添加到不仅仅是点击手势和按钮，我认为我正确地遵循了格式，但仍然得到 'has no member' 错误，这是我的伪代码：

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.handlTap(_:)))

func handleTap(_ sender: AnyObject) {
    }

Answer 1

使用 UITapGestureRecognizer 访问任何对象

  let recognizer = UITapGestureRecognizer(target: self, action: #selector(self.expand))
  view.addGestureRecognizer(recognizer)
  func expand(sender:UITapGestureRecognizer){
   if let myImg = sender.view as? UIImageView //or AnyObject you want {

}
  }

Answer 2

将手势添加到您的视图中：

view.addGestureRecognizer(yourGesture)
