Change the rootviewcontroller of window programaticaly

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

   UIStoryboard *aStoryBoard=[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
   UITabBarController *aTabCtrl=[aStoryBoard instantiateViewControllerWithIdentifier:@"Tab"];
   FirstVC *aFirstCtrl=[aStoryBoard instantiateViewControllerWithIdentifier:@"First"];

   if(self.termsHaveBeenAccepted)
      self.window.rootViewController=aFirstCtrl;

      self.window.rootViewController=aTabCtrl;
   return YES;
}

This will definitely work I have tested.
