iOS 7 - TabBarController does not have text label - ios

Question

I am trying to create an application with a UITabBarController. I have followed several tutorials online and it seems like I'm missing something since my UITabBarController does not have text but you can switch from one View to another.
Here is my didFinishWithLaunchingOptions function:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.tabController = [[UITabBarController alloc] init];
UIViewController *viewController1 = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
ListViewController *listVC = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
self.tabController.viewControllers = [[NSArray alloc] initWithObjects:viewController1, listVC, nil];
self.window.rootViewController = self.tabController;
[self.window makeKeyAndVisible];
[self createCopyOfDatabaseIfNeeded];
return YES;
}
What am I missing out on?

You need to set the tab bar image and title of each view controller:
self.tabController = [[UITabBarController alloc] init];
UIViewController *viewController1 = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
ListViewController *listVC = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
viewController1.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"VC1" image:[UIImage imageNamed:#"tab_ yourViewController.png"] tag:0];
listVC.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"listVC" image:[UIImage imageNamed:#"tab_listvc.png"] tag:1];
self.tabController.viewControllers = [[NSArray alloc] initWithObjects:viewController1, listVC, nil];
It's also possible (and often preferred) to set the tabBarItem for each view controller in viewDidLoad, I.e.:
- (void)viewDidLoad
{
[super viewDidLoad]; // Be a good citizen!
self.tabBarItem = [[UITabBarItem alloc] init...];
...

You can set tabbar item for each view with code
UITabBar *tabBar = self. tabController.tabBar;
UITabBarItem *tabBarItem0 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:1];
[tabBarItem0 setTitle:#"title1"];
[tabBarItem0 setImage:[UIImage imageNamed:#"img1"]];
[tabBarItem1 setTitle:#"title2"];
[tabBarItem1 setImage:[UIImage imageNamed:#"img2"]];
self.window.rootViewController = self.tabController;
[self.window makeKeyAndVisible];
