Swift 3 TapGestureRecognizer選擇器拋出錯誤

Question

我已經看過幾個其他帖子，其中增加了一個目標問題，而不僅僅是點擊手勢和按鈕，我認爲我正確地遵循格式，但仍然得到'has no member 「錯誤，這是我的僞代碼：

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

func handleTap(_ sender: AnyObject) { 
    } 

Answer 1

手勢添加到您的視圖：

view.addGestureRecognizer(yourGesture) 

Answer 2

要與UITapGestureRecognizer訪問任何對象

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 { 

} 
    }
