Question

我的应用的首页包含UITabBarController和tabBar。但是当我pushViewController到UINavigationController时，我的UITabBarController没有显示。

的appdelegate：

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有按钮并单击事件：

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

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

Answer 1

您有UITabBarController作为UINavigationController的rootViewController。并UINavigationController作为您应用的根控制器。相反，您必须将UITabBarController设置为应用的根控制器，并在每个标签中添加UINavigationController。

检查this回答。

Answer 2

首先，您需要创建像所有视图控制器（导航控制器）的数组，如

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

和

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

与你的代码示例相同： -

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;

<强>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像Bellow： -

例如，您有应用程序lonch loginScreen 并且单击login按钮，您需要推送视图控制器，并且该视图控制器包含那些Tabbar。

- (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中的LoginButton操作： -

-(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];

}

Answer 3

您应该尝试使用我的以下代码段

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];

我已经向你展示了tabbarcontroller中两个标签的示例。您可以根据需要自定义它。

享受编程！

uitabbarcontroller没有显示在其他uiviewcontroller上
