1. Use a TabBar Controller as your rootViewController, and set this in your APP Delegate.

   [_window addSubview:rootViewController.view];
   

2. When your APP gets loaded, the tab bar controller comes up first, and by default – The First Tab! You should go to the view controller of your first tab, and in the viewDidLoad of that file, use a ModalViewController to use as a LoginViewController.

   LoginViewController *lvc = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]];
   
   [self presentModalViewController:lvc animated:NO];
   
   [lvc release];
   

3. If you get to this stage, the Login View Controller will pop up right after you launch the app. If login is successful, you can dismiss it

   [self dismissModalViewControllerAnimated:YES];
   

4. If you dismiss it, it will show you the rootController, which is the TabBarController, and this is the approach used by most programmers for login and stuff.
