iOS_深入_UINavigationController VS UIViewController _利用分栏控制器切换视图

效果如下，不同的控制器里面显示不同的导航栏信息：

1、首先在AppDelegate.m里面设置导航栏如下：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

    self.window.rootViewController=[[MainTabbarController alloc]init];

    [self.window makeKeyAndVisible];

    return YES;

}

2、然后在 UITabBarController里的 viewDidLoad中设置 如下：

- (void)viewDidLoad {

    [super viewDidLoad];

    /**设置子控制器*/

    [self createViewControllers];

    /**设置分栏元素*/

    [self setTabBarItems];

}

#pragma mark 导航控制器包装视图控制器

- (void)createViewControllers{

    UINavigationController *navXM = [[UINavigationController alloc]initWithRootViewController:[[XianMianVC alloc]init]];

    UINavigationController *navCP = [[UINavigationController alloc]initWithRootViewController:[[CutPriceVC alloc]init]];

    UINavigationController *navF = [[UINavigationController alloc]initWithRootViewController:[[FreeVC alloc]init]];

    UINavigationController *navST = [[UINavigationController alloc]initWithRootViewController:[[SpecialTopicVC alloc]init]];

    UINavigationController *navHA = [[UINavigationController alloc]initWithRootViewController:[[HotAppVC alloc]init]];

    self.viewControllers=@[navXM,navST,navHA,navF,navCP];

}

#pragma mark 设置分栏元素

- (void)setTabBarItems{}

3、然后在各个[子控制器里面]就可以私人定制自己的导航控制器啦~
