How to make UITextView "Done" button resignFirstResponder?

Question

I am trying to make my editable UITextView resign the keyboard (resignFirstResponder) when the user taps "Done." Using a UITextField, I have been able to do this with the following code:

- (IBAction)doneEditing:(id)sender {
    [sender resignFirstResponder];
}

... and then to attach it to the relevant UITextField in Interface Builder to the action "Did End on Exit."

However, with a UITextView, I can't seem to access the "Did End on Exit" action. Any suggestions on how to make this happen?

The accepted answer didn't work for me. Instead, the following delegate method should be invoked like this:

- (BOOL) textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    if([text isEqualToString:@"\n"]){
        [textView resignFirstResponder];
        return NO;
    }else{
        return YES;
    }
}

Paste that into the class that you assign to be the UITextView delegate and it'll work.
