How to add Done button to the keyboard?

Question

UPDATE:

I also tried implementing UITextViewDelegate delegate and then doing in my controller:

- (BOOL)textViewShouldEndEditing:(UITextView *)textVie         


        

Answer 1

Swift version:

In Your ViewController:

textField.returnKeyType = UIReturnKeyType.Done
textField.delegate = self

After your ViewController

extension MyViewController: UITextFieldDelegate {        
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }
}
