How to make return key on iPhone make keyboard disappear?

Question

I have two UITextFields (e.g. username and password) but I cannot get rid of the keyboard when pressing the return key on the keyboard. How can I do this?

Answer 1

in swift you should delegate UITextfieldDelegate, its important don't forget it, in the viewController, like:

class MyViewController: UITextfieldDelegate{

     mytextfield.delegate = self

     func textFieldShouldReturn(textField: UITextField) -> Bool {
          textField.resignFirstResponder()
     }
}
