And call this on the tab bar controller</p> <pre><code>- (void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated </code></pre> <p><strong>UPDATE 2</strong> </p> <p>Here is a simple code to create a tab bar with two empty views, each has its own tab button.</p> <pre><code>tabBarController = [[UITabBarController alloc]init]; firstView = [[FirstView alloc] init]; UITabBarItem *item1 = [[[UITabBarItem alloc]initWithTitle:@"First" image:nil tag:1] autorelease]; [firstView setTabBarItem:item1]; secondView = [[SecondView alloc] init]; UITabBarItem *item2 = [[[UITabBarItem alloc]initWithTitle:@"Sec" image:nil tag:1] autorelease]; [secondView setTabBarItem:item2]; [tabBarController setViewControllers:[NSArray arrayWithObjects:firstView,secondView,nil] animated:NO]; [window addSubview:tabBarController.view]; </code></pre> <p>Of course this code wont be useful as is, you will need to create the views manually, or create a nib file for each view and load it in <code>initWithNibName</code></p> <p><strong>UPDATE 3</strong><br> Check this <a href="http://deimos3.apple.com/WebObjects/Core.woa/Browse/itunes.stanford.edu.3124430053.03124430055" rel="nofollow noreferrer">Stanford iPhone Course</a>, its a free course from Stanford univ. the lecturers are Apple employees.
