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 = [[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds];

self.window.rootViewController=[[MainTabbarControlleralloc]init];

[self.windowmakeKeyAndVisible];

return YES;

}

2、然后在UITabBarController里的viewDidLoad中设置如下：

- (void)viewDidLoad {

[superviewDidLoad];

/**设置子控制器*/

[selfcreateViewControllers];

/**设置分栏元素*/

[selfsetTabBarItems];

}

#pragma mark 导航控制器包装视图控制器

- (void)createViewControllers{

UINavigationController *navXM = [[UINavigationControlleralloc]initWithRootViewController:[[XianMianVCalloc]init]];

UINavigationController *navCP = [[UINavigationControlleralloc]initWithRootViewController:[[CutPriceVCalloc]init]];

UINavigationController *navF = [[UINavigationControlleralloc]initWithRootViewController:[[FreeVCalloc]init]];

UINavigationController *navST = [[UINavigationControlleralloc]initWithRootViewController:[[SpecialTopicVCalloc]init]];

UINavigationController *navHA = [[UINavigationControlleralloc]initWithRootViewController:[[HotAppVCalloc]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~
