How is a done button added to a keyboard

Question

I have a keyboard which edits text in a UITextView and tapping the return key doenst dismiss the keyboard, it only moves down to the next line.

How can I add a done button and make that dismiss the keyboard?

Answer 1

Implement the textView:shouldChangeTextInRange method to look for "\n" then call resignFirstResponder on the textView if it is found.
