UITextView returnKeyType

Question

I'm trying to change the "Return" key on a UITextView (not UITextField) to a "Done" key. I have the following code that doesn't update the button and leaves the button unchanged. The button starts as a "return" key and if they hit "return" once I want it to change to a "done" key.

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    // this is only run when they hit return once
    textView.returnKeyType = UIReturnKeyDone;
    [textView reloadInputViews];
}

Answer 1

More than a clean solution, this is a bit of a hack. You could try to hide and show the keyboard (i.e. resignFirstResponder, change the return key style and becomeFirstResponder).

But it will produce a weird animation. To avoid this glitch, you should be able to prevent the screen from being refreshed.

BTW, at the end of this method, do you return YES or NO?
