How to make UITextView "Done" button resignFirstResponder?

I am trying to make my editable UITextView resign the keyboard (resignFirstResponder) when the user taps "Done." Using a UITextField, I have been able to do this with the following code:

- (IBAction)doneEditing:(id)sender {
    [sender resignFirstResponder];
}

... and then to attach it to the relevant UITextField in Interface Builder to the action "Did End on Exit."

However, with a UITextView, I can't seem to access the "Did End on Exit" action. Any suggestions on how to make this happen?

You can implement UITextViewDelegate and wait for "\n", in Swift 4 :

    myTextView.delegate = self

// ...

extension MyViewController : UITextViewDelegate {

    func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
        if text == "\n" {
            textView.resignFirstResponder()
            return false
        }

        return true
    }
}
