I want to create an iOS app which consist of a login form which will ask for the person's BASECAMP username and password. when the user enters these details. It should login to his BASECAMP account. How do I do this in Xcode ?

 I have created a login screen and also used a POST method specifying the URL. I am not able to pass the username and password to the BASECAMP URL. How do I do this ?
