UITabBarController

UITabBarController is the typical tab bar you see at the bottom of an iPhone application:

In your App Delegate file, inside the application:didFinishLaunchingWithOptions method:

UITabBarController *tabBarController = [[UITabBarController alloc] init]; NSArray *viewControllers = [NSArray arrayWithObjects: viewController1, viewController2, viewController3, nil]; [tabBarController setViewControllers:viewControllers]; [[self window] setRootViewController:tabBarController];

To set titles, in each controller representing a tab bar item:

- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)bundle {     self = [super initWithNibName:nil bundle:nil];     if (self)     {         UITabBarItem *item = [self tabBarItem];         [item setTitle:@"First"];         UIImage *image = [UIImage imageNamed:@"circle.png"];         [item setImage:image];     }     return self; }
