Selector syntax for swift 3.0

Question

I am trying to add a target to a button this way:

btnAll.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside) 

But this gives me an error:

Using an unresolved identifier 'buttonTapped'

But I declared a function like:

 func buttonTapped(sender: UIButton) { print("All Tapped") } 

Can someone tell me this is the right way to do this in quick 3.

Answer 1

Add a goal like,

should now be written as #selector(buttonTapped(sender:)) or use #selector(buttonTapped(_:))

 btnAll.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside) 

then change your function e.g.

  func buttonTapped(_ sender : UIButton){ .... } 

Answer 2

You can do it as follows:

 btnAll.addTarget(self, action: #selector(buttonTapped(sender:)), for: .touchUpInside)
