Facebook login retrieving user info

This is really a simple task for a programmer knowing titanium facebook module. Generate a project, both for android and ios, with a simple interface (just one button), wich allow user to 'login' with his facebook account without dialog. If not handled by module generate user messages for exceptions (no facebook account, no network and so on) Once logged populate some variables with user informations :email and complete name. Project must be complete with [login to view URL] configured to allow facebook login without dialog. The page will be integrated in an existing project so you have to explain me how to do it, and make the button work, both for android and for ios.
