Asks the delegate if editing should stop� Sourav Gupta's solution partially worked for me however it had a few pitfalls, namely that it didn't correctly call the target code if the editing happened in the middle of the text body (for example: writing a bunch of text, moving the cursor to the middle and then hitting return three times) as well as handling insertion events like pasting and text correction.

Doing so causes the text view object to end the current editing session (with the delegate object’s consent) and hide the keyboard.
