Answer 1

Suppose you have 2 tabs on your tabBarController.

In your appDelegate function

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];

    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];

  self.tabBarController = [[UITabBarController alloc] init];

   self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2,nil];

     self.window.rootViewController = self.tabBarController;
     [self.window makeKeyAndVisible];


}

This way you can easily bind your tabBarController. Note: Dont forget to declare tabBarController in your appDelegate.h file.
