How to detect delete key on an UITextField in iOS 8?

Question

I have subclassed UITextField and implemented the UIKeyInput protocol\'s deleteBackward method to detect backspace being pressed. This works fine on iOS 7 but not on iOS 8.<

Answer 1

Swift 2.2:

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {

    if text == "" {
      print("Backspace has been pressed")
    }

    return true
}
