UIView touch event in controller

Question

How can I add UIView touchbegin action or touchend action programmatically as Xcode is not providing from Main.storyboard?

Answer 1

You will have to add it through code. First, create the view and add it to the hierarchy:

var myView = UIView(frame: CGRectMake(100, 100, 100, 100)) self.view.addSubview(myView)  

After that initialize gesture recognizer. Until Swift 2:

let gesture = UITapGestureRecognizer(target: self, action: "someAction:") 

After Swift 2:

let gesture = UITapGestureRecognizer(target: self, action:  #selector (self.someAction (_:))) 

Then bind it to the view:

self.myView.addGestureRecognizer(gesture)       

Swift 3:

func someAction(_ sender:UITapGestureRecognizer){        // do other task }      

Swift 4 just add @objc before func:

@objc func someAction(_ sender:UITapGestureRecognizer){          // do other task } 

Swift UI:

Text("Tap me!").tapAction {     print("Tapped!") }

Swift 4 / 5:

let gesture = UITapGestureRecognizer(target: self, action:  #selector(self.checkAction)) self.myView.addGestureRecognizer(gesture)  @objc func checkAction(sender : UITapGestureRecognizer) {     // Do what you want } 

Swift 3:

let gesture = UITapGestureRecognizer(target: self, action:  #selector(self.checkAction(sender:))) self.myView.addGestureRecognizer(gesture)  func checkAction(sender : UITapGestureRecognizer) {     // Do what you want }
