how does UITextView delegate knows when to call textViewDidEndEditing

Question

I am developing an application in which i need to call a perticular method when user hits return button.I am using UITextView.Now the problem is that when i hit return key ,cursor goes to next line and i am not able to retrive the action in my code.I tried to write the same code in textViewDidEndEditing: delegate method but it looks as if we cant find when and at what action this perticular method is called...Can someone help in with any of above approach?

To detect the return key, you could implement the following delegate method:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text

Simply check text for a newline and proceed as desired.
