Используйте следующие оборотный штраф для меня:

-(void)LinkeToFaceBook:(NSString *)stringRequest{ 

     if ([HostSite checkServerConnected :kNetworkSuccess withFailureNote:kNetworkFailure]) 
     { 
      if (!FBSession.activeSession.isOpen) { 
       [FBSession.activeSession closeAndClearTokenInformation]; 
       FBSession.activeSession=nil; 
       [self openFacebookAuthentication]; 
      } 
     } else { 
      [self networkAlertShow]; 

     } 

    } 

    -(void)openFacebookAuthentication 
    { 
     NSArray *permission = [NSArray arrayWithObjects:kFBEmailPermission,kFBUserPhotosPermission,kFBUserPublicPermission,kFBUserLikePermission, nil]; 

     FBSession *session = [[FBSession alloc] initWithPermissions:permission]; 

     [FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission] ]; 

     [[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) { 

      switch (status) { 
       case FBSessionStateOpen: 
        [self likeFaceBook]; 
        break; 
       case FBSessionStateClosedLoginFailed: { 
        // prefer to keep decls near to their use 
        // unpack the error code and reason in order to compute cancel bool 
        NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode]; 
        NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason]; 
        BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]); 
        if(error.code == 2) { 
         UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle 
                       message:kFBAuthenticationErrorMessage 
                       delegate:nil 
                    cancelButtonTitle:kOk 
                    otherButtonTitles:nil]; 
         [errorMessage performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES]; 
         errorMessage = nil; 
        } 
       } 
        break; 
        // presently extension, log-out and invalidation are being implemented in the Facebook class 
       default: 
        break; // so we do nothing in response to those state transitions 
      } 
     }]; 
     permission = nil; 
    }
