insertText:

[twestley]

I'm planning to use this but I've changed KOKeyboardRow insertText: as follows:

- (void)insertText:(NSString *)text
{
    if (textView.delegate && [textView.delegate
        respondsToSelector:@selector(textView:shouldChangeTextInRange:replacementText:)])
    {
        if ([textView.delegate textView:textView
            shouldChangeTextInRange:textView.selectedRange
                    replacementText:text])
        {
            [textView insertText:text];
        }
    }
    else
    {
        [textView insertText:text];
    }
}
