                             NSLog(@"user id %@",user.id);
                             NSLog(@"Email %@",[user objectForKey:@"email"]);
                             NSLog(@"User Name %@",user.username);
                         }
                     }];
                }
            }];

Problem

The code I have used ``` if (FBSession.activeSession.state == FBSessionStateOpen || FBSession.activeSession.state == FBSessionStateOpenTokenExtended) { // Close the session and remove the access token from the cache // The session state handler (in the app delegate) will be called automatically [FBSession.activeSession closeAndClearTokenInformation]; // If the session state is not any of the two "open" states when the button is clicked } else { // Open a session showing the user the login UI // You must ALWAYS ask for basic_info permissions when opening a session [FBSession openActiveSessionWithReadPermissions:@[@"basic_info,email"] allowLoginUI:YES completionHandler: ^(FBSession *session, FBSessionState state, NSError *error) { // Retrieve the app delegate AppDelegate* appDelegate = [UIApplication sharedApplication].delegate; // Call the app delegate's sessionStateChanged:state:error method to handle session state changes [appDelegate sessionStateChanged:session state:state error:error]; }]; } ``` from this code i need to get user name and mail id. if any one know the solution please help me thanks in advance.
