extension UITextField {
    func addDoneButtonOnKeyBoardWithControl() {
	let keyboardToolbar = UIToolbar(frame: CGRect(0, 0, UIScreen.main.bounds.width, 44))
	keyboardToolbar.sizeToFit()
	keyboardToolbar.barStyle = .default
	let flexBarButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
	let doneBarButton = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(self.endEditing(_:)))
	keyboardToolbar.items = [flexBarButton, doneBarButton]
	self.inputAccessoryView = keyboardToolbar
    }
}

Then just call this on your textfield.

I am unsure what you mean by call this on your textfield?

thanks! It's useful
