                                  // Handler for session state changes
                                  // This method will be called EACH time the session state changes,
                                  // also for intermediate states and NOT just when the session open
                                  [self sessionStateChanged:session state:state error:error];

Where you add your code for `'sessionStateChanged:state:error:`? — Mani, Jan 27 '14 at 11:01
Mani i followed this link https://developers.facebook.com/docs/ios/login-tutorial it is the first step but it is showing the error — Peer Mohamed Thabib, Jan 27 '14 at 11:04
Did you see this `Handling session state changes` topic? Did you add this? — Mani, Jan 27 '14 at 11:06
You have to add this method. because you already add this call(`self sessionStateChanged:session.....`) in your block. — Mani, Jan 27 '14 at 11:10

According to above link, You have to add this method in your app delegate.. But you can customize this method according to your view by state(state == FBSessionStateOpen... etc)

// This method will handle ALL the session state changes in the app
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState) state error:(NSError *)error
{
  // If the session was opened successfully
  // customize your code...
}
