generally you would want the login to be a modal, and the tabBar to be the root view controller. this way if the user is already logged in and has his session cached on disk, he doesnt have to go through and login again. The tabBarController just comes up.

You need to perform a check in viewDidAppear of the first tabBarController's viewController to see if the user is logged in, if hes not, segue to the login view controller, if he is logged in, you dont really have to do anything.

//in the app delegate.h @property(strong,nonatomic)UITabBarController *tabBarController; // in the app delegate.m

                    UIStoryboard *storyboard=[UIStoryboard storyboardWithName:@"Main" bundle:nil];
                   UITabBarController *tabBarController =(UITabBarController*)self.window.rootViewController;

                    LoginViewController *logincontroller=[storyboard instantiateViewControllerWithIdentifier:@"log"];

                      [tabBarController presentViewController:logincontroller animated:YES completion:NULL];
