本文介绍如何在iOS应用中设置带有导航控制器（Navigation Controller）的TabBar，并提供了一个不需要导航控制器的TabBar实现示例。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    FirstViewController *firstViewController=[[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
    UINavigationController *navControl1=[[UINavigationController alloc]initWithRootViewController:firstViewController];
    [firstViewController release];
    
    SecondViewController *secondViewController=[[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
    UINavigationController *navControl2=[[UINavigationController alloc]initWithRootViewController:secondViewController];
    [secondViewController release];
    
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

    self.tabBarController = [[[UITabBarController alloc] init] autorelease];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navControl1, navControl2, nil];
    
    [navControl1 release];
    [navControl2 release];
    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];
    return YES;
}

如果某个tabBar不需要navigation，那么用如下代码初始化对应的control

UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];
