Swift 3 TapGestureRecognizer选择器抛出错误

Question

我已经看过几个其他帖子，其中增加了一个目标问题，而不仅仅是点击手势和按钮，我认为我正确地遵循格式，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

手势添加到您的视图：

view.addGestureRecognizer(yourGesture) 

Answer 2

要与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 { 

} 
    }
