UINavigationController 以及 UITabBarController

UINavigationController相關代碼如下

    for (UIViewController *next in self.navigationController.viewControllers) {
        if ([next isKindOfClass:[ShoppingCenter class]]) {
            [self.navigationController popToViewController:next animated:YES];
        }
    }

UITabBarController相關代碼如下:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];
    TRRootAViewController *avc = [[TRRootAViewController alloc]initWithNibName:@"TRRootAViewController" bundle:nil];
    
    //設置avc爲rootVC
    UINavigationController *aNvc = [[UINavigationController alloc]initWithRootViewController:avc];
    avc.title=@"金融超市";
    avc.tabBarItem.badgeValue = @"1"; //徽標
    avc.tabBarItem.image = [UIImage imageNamed:@"tab_0.png"];
    
    //設置VC的title以及圖片 -->圖片大小 22*22
    TRrootBViewController *greenvc = [[TRrootBViewController alloc]initWithNibName:@"TRrootBViewController" bundle:nil];
        UINavigationController *greenNvc = [[UINavigationController alloc]initWithRootViewController:greenvc];
    greenvc.title = @"掌上銀行";
    greenvc.tabBarItem.image = [UIImage imageNamed:@"tab_1.png"];
  
    
    TRRootCViewController *bluevc = [[TRRootCViewController alloc]initWithNibName:@"TRRootCViewController" bundle:nil];
        UINavigationController *blueNvc = [[UINavigationController alloc]initWithRootViewController:bluevc];
    bluevc.title = @"掌上股市";
    bluevc.tabBarItem.image = [UIImage imageNamed:@"tab_2.png"];
    
    TRRootDViewController *blackvc = [[TRRootDViewController alloc]initWithNibName:@"TRRootDViewController" bundle:nil];
        UINavigationController *blackNvc = [[UINavigationController alloc]initWithRootViewController:blackvc];
    blackvc.title = @"信用卡";
    blackvc.tabBarItem.image = [UIImage imageNamed:@"tab_3.png"];
    blackvc.tabBarItem.badgeValue = @"5"; //徽標
    
    TRrootEViewController *Evc = [[TRrootEViewController alloc]initWithNibName:@"TRrootEViewController" bundle:nil];
    Evc.title = @"我的";
    
    TRRootFViewController *Fvc = [[TRRootFViewController alloc]initWithNibName:@"TRRootFViewController" bundle:nil];
     Fvc.title = @"你的";
    
    //設置UITabBarController的子視圖
    UITabBarController *tab = [[UITabBarController alloc]init];
    tab.viewControllers = @[aNvc,greenNvc,blueNvc,blackNvc,Evc,Fvc];
    tab.delegate = self;
    
    //設置window的rootVC
    self.window.rootViewController = tab;
    [self.window makeKeyAndVisible];
    return YES;
}
