title: UITabBarController Does not shows tabbarItems name
body: <p>I am creating app based on UTabbarController. I have creates that tab bar programmatically. Everything is running fine except I can not see the tabBatItem title. I have initialized everything properly, but when application launches all I can see is the first tabbar title. but if I select 2nd tabbaritem or so on I can see their names. I don't know whats going wrong here. Here is my code. Please let me know if I made any mistake.</p>
  
  <p>Thanks.</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
  self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
  
      HomeViewController *viewController1 = [[HomeViewController alloc] initWithNibName:@"HomeViewController" bundle:nil];
  UINavigationController*navController1=[[UINavigationController alloc]initWithRootViewController:viewController1];
  navController1.title=@"Home";
  [viewController1 release];
