In IB's library, the introduction tells us that when the return key is pressed, the keyboard for UITextView will disappear. But actually the return key can only act as '\n'.

I can add a button and use [txtView resignFirstResponder] to hide the keyboard. But is there a way to add the action for the return key in keyboard so that I needn't add another button.
