Answer 1

You don't need a splash screen controller unless you are animating something. This example uses NSUserDefaults to remember if it's first login or not.

In you application delegate put the following:

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
   {


        self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

        if(![[NSUserDefaults standardUserDefaults] dictionaryForKey:@"someKey"]){
            UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"registerViewController"];
            self.window.rootViewController = viewController;
        } else {
            UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"mainViewController"];
            self.window.rootViewController = viewController;
        }

        [self.window makeKeyAndVisible];



         return YES;
  }

If you decide you must have a viewcontroller for the splash screen then you can put the same code there.
