Hi...

textField:shouldChangeCharactersInRange:replacementString just tells you what the most recent character is that got typed (if range == 0) or got backspaced over (if range == 1).

You have to use other methods to actually change the contents of the text field. You manipulate the text field's text property directly with methods like replaceOccurrencesOfString:withString: or insertString:atIndex: or deleteCharactersInRange:, and so on. See the NSString instance methods for all the goodies available.
