Question

我是iOS新手，在Xcode 6更新后，我在 taBbar 中显示导航控制器时遇到了麻烦。

使用Xcode 5，它运行得很好但是现在在模拟器上我收到一条错误消息“因未捕获的异常而终止应用程序'NSInvalidArgumentException'，原因：'不支持推送导航控制器' “而应用程序崩溃了。这是我的代码：

**appDelegate.m**

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

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor =[UIColor whiteColor];
[self.window makeKeyAndVisible];

*// tabBar items*

ItemUnViewController *itemUnViewController = [[ItemUnViewController alloc]
                                                          initWithNibName:nil
                                                          bundle:NULL];


ItemDeuxViewController *itemDeuxViewController = [[ItemDeuxViewController alloc]
                                                                initWithNibName:nil
                                                                bundle:NULL];

*//tabBar*

UITabBarController *tabBarController = [[UITabBarController alloc] init];

[tabBarController setViewControllers:@[itemUnViewController,itemDeuxViewController]];


*//setting tabBar as rootView*

self.window.rootViewController = tabBarController;


*// navigation Controllers*

UINavigationController *itemUnNavigationController =
[[UINavigationController alloc]
initWithRootViewController:itemUnViewController];

UINavigationController *itemDeuxNavigationController =
[[UINavigationController alloc]
initWithRootViewController:itemDeuxViewController];


*//Combining tabBar and Navigation Controllers*

[tabBarController setViewControllers:@        
[itemUnNavigationController,itemDeuxNavigationController]];

return YES;
}

我甚至尝试过这种方式http://blog.rifkilabs.net/exploring-navigation-controller-and-tab-bar-controller.html，但我得到了同样的错误信息。

感谢您的帮助。

结合TabBar和导航控制器IOS8
