    <p>I just can't for the life of me get a navigation controller (and bar) in each of my tab bar item views. Here is my appdelegate , what am I missing? <code>FrontPage</code> and <code>Opinion</code> are tableviewcontrollers as well, just forgot the table in their names.</p> <pre><code>@implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. FrontPageViewController *frontPageVC = [[FrontPageViewController alloc] initWithNibName:nil bundle:nil]; frontPageVC.title = @"Front Page"; frontPageVC.tabBarItem.image = [UIImage imageNamed:@"second"]; UINavigationController *frontPageNavController = [[UINavigationController alloc] initWithRootViewController:frontPageVC]; CampusTableViewController *campusVC = [[CampusTableViewController alloc] initWithNibName:nil bundle:nil]; campusVC.title = @"Campus"; campusVC.tabBarItem.image = [UIImage imageNamed:@"second"]; UINavigationController *campusNavController = [[UINavigationController alloc] initWithRootViewController:campusVC]; OpinionViewController *opinionVC = [[OpinionViewController alloc] initWithNibName:nil bundle:nil]; opinionVC.title = @"Opinion"; opinionVC.tabBarItem.image = [UIImage imageNamed:@"second"]; UINavigationController *opinionNavController = [[UINavigationController alloc] initWithRootViewController:opinionVC]; SportsTableViewController *sportsVC = [[SportsTableViewController alloc] initWithNibName:nil bundle:nil]; sportsVC.title = @"Sports"; sportsVC.tabBarItem.image = [UIImage imageNamed:@"second"]; UINavigationController *sportsNavController = [[UINavigationController alloc] initWithRootViewController:sportsVC]; PDFViewController *pdfVC = [[PDFViewController alloc] initWithNibName:nil bundle:nil]; NSArray *controllers = [NSArray arrayWithObjects:frontPageVC, campusVC, opinionVC, sportsVC, pdfVC, nil]; self.tabBarController = [[UITabBarController alloc] init]; self.tabBarController.viewControllers = controllers; self.window.rootViewController = self.tabBarController; [self.window makeKeyAndVisible]; return YES; [[self.tabBarController.viewControllers objectAtIndex:0] setRootViewController:frontPageNavController]; } </code></pre> <p>thank you!</p> <p>edit: apparently I need to type more to explain my problem because SO won't let me post without a certain amount of words?</p>

    1. COI think the problem is your with `initWithNibName = nil`....you must pass you `.Nib` name to it.. for exa... `FrontPageViewController *frontPageVC = [[FrontPageViewController alloc] initWithNibName:@"FrontPageViewController".... `!!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
