copied!<p>I've got it! This is my delegate method implementation for the <code>shouldChangeCharactersInRange</code> method.</p> <hr> <pre><code>- (BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange) range replacementString:(NSString *) string { if ([string isEqualToString:@"⌫"]) { // NSLog(@"Backspace Pressed"); NSMutableString *text = [textField.text mutableCopy]; // NSLog(@"Length: %d Location: %d", range.length, range.location); if (range.length > 0) { [text deleteCharactersInRange:range]; } if (range.length == 0 && range.location != 0) { NSRange backward = NSMakeRange(range.location - 1, 1); // NSLog(@"Length: %d Location: %d", backward.length, backward.location); [text deleteCharactersInRange:backward]; } // NSLog(@"%@", text); textField.text = text; return NO; } else {return YES;} } </code></pre> <p>It works hand in hand with the <a href="http://dev.ragfield.com/2009/09/insert-text-at-current-cursor-location.html">UIPasteboard method</a> for getting text into a <code>UITextField</code>, which means that you have to link up your delete key to a method that pastes an arbitrary unicode character into your textfield (such as <code>⌫</code>), and when the delegate method is called, you recognise that the replacement string is that specific character.</p> <p>From there, you either delete the characters in <code>range</code> from your mutable string of the textField's text if there is an active selection, or you grab the previous character from the range if there is no selection, just a caret.</p>
