1. See NSNumberFormatter and its setMaximum: method.
2. See NSURLConnection
3. What's a faded button? Do you mean a hidden button (setHidden? Set all your text fields' delegates to your controller and implement the controlTextDidChange: method, then check each text field to see if its stringValue's length is 0.
