【问题描述】：

我的应用有一个包含UITabBarController 和tabBar 的第一页。但是当我 pushViewController 到 UINavigationController 时，我的 UITabBarController 没有显示。

应用代理：

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
anasayfaViewController * firstTab= [[anasayfaViewController alloc] initWithNibName:@"anasayfaViewController" bundle:nil];
SehirRehberiViewController *sehirRehberi = [[SehirRehberiViewController alloc] initWithNibName:@"SehirRehberiViewController" bundle:nil];
duyuruViewController *duyuru = [[duyuruViewController alloc] initWithNibName:@"duyuruViewController" bundle:nil];
sikayetViewController *sikayet = [[sikayetViewController alloc] initWithNibName:@"sikayetViewController" bundle:nil];
digerViewController *diger = [[digerViewController alloc] initWithNibName:@"digerViewController" bundle:nil];

self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = @[firstTab,sehirRehberi,duyuru,sikayet,diger];
        navigationController=[[UINavigationController alloc]initWithRootViewController:self.tabBarController];

self.window.rootViewController = self.navigationController;
// [self.window addSubview:self.navigationController.view];
[self.window makeKeyAndVisible];

return YES;

firstTab viewcontroller 有按钮和点击事件：

-(void)btnClick:(id)sender
{
    [self.navigationController pushViewController:haberler animated:NO];
}

当我单击UIViewController 时，它正在打开，但没有显示UITabBarController。我怎么解决这个问题？

【问题讨论】：

您想在标签栏控制器中添加导航控制器吗？你现在有相反的方式，所以新视图被推到标签栏上
@Leta0n haberler 是 uiviewcontroller

标签： iphone objective-c uinavigationcontroller uitabbarcontroller

【解决方案1】：

您将UITabBarController 作为UINavigationController 的rootViewController。并且UINavigationController 作为您的应用程序的根控制器。取而代之的是，您必须将 UITabBarController 设置为应用程序的根控制器，并在每个选项卡中添加 UINavigationController。

检查this的答案。

感谢 Valantin 的回答。但是当我点击按钮时，我可以在哪里 pushViewController ？那么哪个导航控制器？
你从你的一个标签里面的 navigationController 推送新的控制器。

【解决方案2】：

你应该尝试使用我的以下 sn-p

anasayfaViewController * firstTab= [[anasayfaViewController alloc] initWithNibName:@"anasayfaViewController" bundle:nil];
    UINavigationController *firstNav = [[UINavigationController alloc] initWithRootViewController:firstTab];

    SehirRehberiViewController *sehirRehberi = [[SehirRehberiViewController alloc] initWithNibName:@"SehirRehberiViewController" bundle:nil];
    UINavigationController *secondNav = [[UINavigationController alloc] initWithRootViewController:sehirRehberi];

// object for tabbarviewcontroller
self.tab.viewControllers = [NSArray arrayWithObjects:firstNav,secondNav,nil];

我已经向您展示了 tabbarcontroller 中两个选项卡的示例。您可以根据需要对其进行自定义。

享受编程！

【解决方案3】：

首先，您需要创建所有视图控制器（导航控制器）的数组

self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationController2,navigationController1,navigationController3,nil];

和

你需要设置Winodw的Rootviewcontroller是 [self.window setRootViewController:tabBarController]; 不是导航控制器

与您的代码示例一样：-

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

anasayfaViewController * firstTab= [[anasayfaViewController alloc] initWithNibName:@"anasayfaViewController" bundle:nil];
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:firstTab];

SehirRehberiViewController *sehirRehberi = [[SehirRehberiViewController alloc] initWithNibName:@"SehirRehberiViewController" bundle:nil];
UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:sehirRehberi];

duyuruViewController *duyuru = [[duyuruViewController alloc] initWithNibName:@"duyuruViewController" bundle:nil]; 
UINavigationController *navigationController3 = [[UINavigationController alloc] initWithRootViewController:duyuru];

sikayetViewController *sikayet = [[sikayetViewController alloc] initWithNibName:@"sikayetViewController" bundle:nil];
UINavigationController *navigationController4 = [[UINavigationController alloc] initWithRootViewController:sikayet];

digerViewController *diger = [[digerViewController alloc] initWithNibName:@"digerViewController" bundle:nil];
UINavigationController *navigationController5 = [[UINavigationController alloc] initWithRootViewController:diger];


self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = @[navigationController1,navigationController2,navigationController3,navigationController4,navigationController5];

 [self.window setRootViewController:tabBarController];
 [self.window makeKeyAndVisible];

return YES;

更新：-

如果你想 TabbarController 添加按钮 Click for NextViewcontroller 那么你可以用不同的方式来做，比如 Bellow :-

例如，您有 loginScreen，而应用程序 lonch 并单击 login 按钮，您需要推送一个视图控制器，并且该视图控制器包含这些选项卡。

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

    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    LoginViewcontroller *objLogin = [[LoginViewcontroller alloc] initWithNibName:@"LoginViewcontroller" bundle:nil];
    self.navigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];


     self.window.rootViewController = self.navigationController;
     [self.window makeKeyAndVisible];
     return YES;
}

在 loginViewcontroller LoginButton 动作中：-

-(IBAction)LoginSuccess
{

    anasayfaViewController * firstTab= [[anasayfaViewController alloc] initWithNibName:@"anasayfaViewController" bundle:nil];
    UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:firstTab];

    SehirRehberiViewController *sehirRehberi = [[SehirRehberiViewController alloc] initWithNibName:@"SehirRehberiViewController" bundle:nil];
    UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:sehirRehberi];

    duyuruViewController *duyuru = [[duyuruViewController alloc] initWithNibName:@"duyuruViewController" bundle:nil]; 
    UINavigationController *navigationController3 = [[UINavigationController alloc] initWithRootViewController:duyuru];

    sikayetViewController *sikayet = [[sikayetViewController alloc] initWithNibName:@"sikayetViewController" bundle:nil];
    UINavigationController *navigationController4 = [[UINavigationController alloc] initWithRootViewController:sikayet];

    digerViewController *diger = [[digerViewController alloc] initWithNibName:@"digerViewController" bundle:nil];
    UINavigationController *navigationController5 = [[UINavigationController alloc] initWithRootViewController:diger];


    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = @[navigationController1,navigationController2,navigationController3,navigationController4,navigationController5];

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

}
