由于Main.storyboard不提供Xcode,如何以编程方式添加UIView touchbegin动作或touchend动作?
您将不得不通过代码添加它。试试这个:
// 1.create UIView programmetically var myView = UIView(frame: CGRectMake(100, 100, 100, 100)) // 2.add myView to UIView hierarchy self.view.addSubview(myView) // 3. add action to myView let gesture = UITapGestureRecognizer(target: self, action: "someAction:") // or for swift 2 + let gestureSwift2AndHigher = UITapGestureRecognizer(target: self, action: #selector (self.someAction (_:))) self.myView.addGestureRecognizer(gesture) func someAction(sender:UITapGestureRecognizer){ // do other task } // or for Swift 3 func someAction(_ sender:UITapGestureRecognizer){ // do other task } // or for Swift 4 @objc func someAction(_ sender:UITapGestureRecognizer){ // do other task } // update for Swift UI Text("Tap me!") .tapAction { print("Tapped!") }
