    Hey, I'm not sure how to refer to this.. I think its a string format but thought I would come here to get some help.

    I am wanting to get my user to enter a 20 character string, they will be numbers and I want to after every fifth number to insert a hyphen.. as the person is typing... how can this be done?

    this would take a bit of work i think, but u should use the delegate method of a textField, didchangecharactersinrange or somewhat?
    Think that should set u off..
