I am using the text field delegate method "shouldChangeCharactersInRange" and I wanted to know if there is any way to tell if user is deleting characters or typing characters? Anyone know? thanks.

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if (range.length > 0)
    {
         // We're deleting
    }
    else
    {
        // We're adding
    }
}
