整合TabBarController与NavigationController

一、项目结构

　　一开始创建一个空的项目

　　

二、主要代码

　　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=@"联系人";

    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=@"添加联系人";

    [self.navigationController pushViewController:childViewController animated:YES];

}

　　3、SecondViewController.m

　　　  默认内容

　　4、ChildViewController.m

　　　  默认内容

三、运行效果

　　1、初始界面

　　

　　2、进入第一个视图的子视图

　　

　　3、切换到第二个视图
