Swift3 Swift 3 TapGestureRecognitor选择器抛出错误

我看了另外两篇文章，其中涉及到添加目标的问题，不仅仅是点击手势和按钮，我认为我正确地遵循了格式，但仍然出现了“没有成员”错误，下面是我的伪代码：

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

func handleTap(_ sender: AnyObject) {
    }

使用UITapGestureRecognitor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 {

}
  }

将手势添加到视图中：

view.addGestureRecognizer(yourGesture)
