Apple says this application was banned because it used a non-public API.
You will need to upload a picture of yourself to the application - this can be either from your computer or by accessing the Facebook API (using your username and password).
Facebook also has its own "Graph API" which is used to measure people, photos, events, and pages as well as the connections between them.
It also uses both basic and advanced API methods, such as web-based authentication and real-time updates.
When someone generates docs, the -link option generates links to documentation for any API referenced by the API being documented.
