[摘要]本文是對整合TabBarController與NavigationController的講解，對學習IOS蘋果軟件開發有所幫助,與大家分享。

一、項目結構

　　一開始創建一個空的項目

　　

二、主要代碼

　　1、AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    
    UITabBarController *tabBarController = [[UITabBarController alloc] init];
    
    FirstViewController *one = [[FirstViewController alloc] init];
    one.title=@"聯系人";
    one.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemContacts tag:0];
    UINavigationController *navFirst = [[UINavigationController alloc] initWithRootViewController:one];
    [tabBarController addChildViewController:navFirst];
    
    SecondViewController *two = [[SecondViewController alloc] init];
    two.title=@"收藏";
    two.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:1];
    UINavigationController *navSecond = [[UINavigationController alloc] initWithRootViewController:two];
    [tabBarController addChildViewController:navSecond];

    
    self.window.rootViewController=tabBarController;
    
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

　　2、FirstViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(selectRightAction:)];
    self.navigationItem.rightBarButtonItem = rightButton;
}

-(void)selectRightAction:(id)sender
{
    ChildViewController *childViewController;
    childViewController =[[ChildViewController alloc] initWithNibName:@"ChildViewController" bundle:nil];
    childViewController.title=@"添加聯系人";
    [self.navigationController pushViewController:childViewController animated:YES];
}

　　3、SecondViewController.m

　　　 默認內容

　　4、ChildViewController.m

　　　 默認內容

三、運行效果

　　1、初始界面

　　

　　2、進入第一個視圖的子視圖

　　

　　3、切換到第二個視圖
