I used FriendPickerSample app which came with the Facebook IOS SDK to display a list of my user's Facebook friends. I get an array of FBGraphUser back and can access the id, first_name, last_name, link and address properties.
Now I want to send these users a message inviting them to download our app. What is the next step? Should I not be using FBFriendPickerViewController? If not then what is the right way to do this?
