You can find more descriptive example from Apple docs - Combined View Controller Interfaces

I assume that Login Page is your root view controller here. Where _tabBar, _window and _loginvVewController are globally declared in the appDelegate headers files. You can also take _loginvVewController locally inside the didFinishLaunchingWithOptions method depend upon your requirements.

AppDelgate.h

UIWindow *_window;
UITabBarController *_tabBar;
LoginViewController *_loginvVewController;

AppDelegate.m

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    self.loginvVewController = [[LoginViewController alloc] init];

    // Add the tab bar controller's current view as a subview of the window
    [self.window addSubview:self.loginvVewController.view]; 

    [self.window makeKeyAndVisible];
    return YES;
}

- (void)initializeTabbar {

    /*
     * Set up controllers for the tab bar controller
     */
    EmployeeViewController *vc1 = [[[EmployeeViewController alloc] initWithTitle:@"View 1"] autorelease];
    TaskViewController *vc2 = [[[TaskViewController alloc] initWithTitle:@"View 2"] autorelease];
    HomeViewController *vc3 = [[[HomeViewController alloc] initWithTitle:@"View 3"] autorelease];

    // View Controller with each Navigational stack support.
    UINavigationController *navController = [[UINavigationController alloc]
                                             initWithRootViewController:vc1];

    /*
     * Set up tab bar controller
     */
    self.tabBar = [[UITabBarController alloc] init]; 
    self.tabBar.viewControllers = [NSArray arrayWithObjects:navController, vc2, vc3, nil];

    [self.window addSubview:self.tabBar.view];
}

In my quick hackathon for this problem, I have taken the button "Click here!" on login page - once you click on it will navigate you inside the app with tabbar. If you need the sample project then email me at d3minem@gmail.com.

After many requests via email - I have created the demo project and upload here. https://github.com/Deminem/SimpleTabbarApp--iPhone-

Please vote if you find it useful.

Good luck!

The better way would be to create a TabBarContoller based application and add the ViewControllers to the TabbarViewController.

The path is straight forward.

In IB, place your tabbar controller where you like it, make it have three pages and set their view controller classes.

Or in code, just add the tab bar controller with those three controllers set as its view controllers.
