UIView touch event in controller
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
}
