Facebook iOS SDK doesn’t handle the session storage. FBSessionDelegate is a callback interface that your application should implement. it's methods will be invoked on application's successful login or logout.

See the example application facebook-ios-sdk/sample/DemoApp/Classes/DemoAppViewController.m for fbDidLogin, fbDidNotLogin and fbDidLogout methods
