TabBarController and NavigationController

Question

I am making an application but I'm still a beginner and I'm trying to get used to the RootViewController and how it should be set.

At the beginning my application launches, I want there to be a View which is not in my tabBarController (which is set to be my rootViewController).

What I am trying to ask is, Can I have another view which is outside my UITabBarController launch first without it being in the tabBarController's items list?

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.

    FacebookFeedViewController *facebookClass = [[FacebookFeedViewController alloc] initWithNibName:@"FacebookFeedViewController" bundle:nil];

    TwitterFeedViewController *twitterClass = [[TwitterFeedViewController alloc] initWithNibName:@"TwitterFeedViewController" bundle:nil];
    LinkedInFeedViewController *linkClass = [[LinkedInFeedViewController alloc] initWithNibName:@"LinkedInFeedViewController" bundle:nil];
    FTLFullFeedViewController *masterClass = [[FTLFullFeedViewController alloc] initWithNibName:@"FTLFullFeedViewController" bundle:nil];

    ///   tab button title

    facebookClass.title = @"Facebook";
    twitterClass.title = @"Twitter";
    linkClass.title=@"LinkedIn";
    masterClass.title=@"FTL";

    // tab button Images
    facebookClass.tabBarItem.image = [UIImage imageNamed:@"facebook_32"];
    twitterClass.tabBarItem.image = [UIImage imageNamed:@"twitter_32"];

    WelcomeViewController *welcomeClass= [[WelcomeViewController alloc] initWithNibName:@"WelcomeViewController" bundle:nil];

    navController = [[ UINavigationController alloc] initWithRootViewController:welcomeClass];

    UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:facebookClass];
    UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:twitterClass];
    UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:linkClass];
    UINavigationController *navController5 = [[UINavigationController alloc] initWithRootViewController:masterClass];

    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController,navController5,navController2,navController3,navController4,nil];
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    return YES;
}

No no, I am not using storyboards. I would love to find out how the navigations of apps work programatically first. — Vlatko Svegjan, Jun 24 '13 at 13:46
Are you using XIBs or creating your view controllers from scratch? — Dan, Jun 24 '13 at 13:50

yes! ofcourse you do.

[self.view addsubview:yourTabbar.view];

Hope this will help you.

Should I use this in the appDelegate or in the view I want to show the tabBar at? – Vlatko Svegjan Jun 24 '13 at 13:40
It's overlapping the view, how do i remove the view below? – Vlatko Svegjan Jun 24 '13 at 13:49
you need to add navigation controller in appDelegate. After that when to navigate viewController-->subviewController. here you add the tabbar. – Sudhir Kumar Jun 24 '13 at 14:39

I know you already selected an answer but all that's doing is pushing a UITabBar view on top of an existing view, not creating a new UITabBarController view. Based on our brief conversation (latest XCode, no StoryBoards, using XIBs) you're going to want to create a xib as a UITabBarController then push it into view...

View *view = [[View alloc] initWithNibName:@"myUITabBarXIB" bundle:nil];
view.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: view animated:YES];

This will present your XIB file but not on top of the existing view controller when the desired action takes place.

Thank you very much for this answer. It makes much more sense and it was just what I needed. Hope I can help you out with something in the future. Thanks again. — Vlatko Svegjan, Jun 24 '13 at 14:38
