标签栏视图不会加载

Question

在我的应用程序委托接口我：

@interface pivcalc1AppDelegate : NSObject <UIApplicationDelegate> { 
UIWindow *window; 
IBOutlet UITabBarController *RootController; 

} 
@property (nonatomic, retain) IBOutlet UIWindow *Window; 
@property (nonatomic, retain) IBOutlet UITabBarController *RootController; 

实施

，我有：

@synthesize Window; 
@synthesize RootController; 

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

[Window addSubview:RootController.view]; 
// Override point for customization after application launch. 
[self.Window makeKeyAndVisible]; 
return YES; 
} 

在我的主要厦门国际银行窗口，我有一个标签栏控制器，该控制器以rootController身份连接到应用程序委托。 当我运行该程序时，窗口显示，但标签栏视图不会被加载。 感谢任何帮助。谢谢。

你在xib的RootController中有一个subViewController吗？如果你不是，它的代码如下。

UITabBarController应该有一个subViewController。

UINavigationController *localNavigationController; 

    NSMutableArray *localViewControllerArray = [[NSMutableArray alloc] initWithCapacity:2]; 

    SubViewController *subviewController0 = [[SubViewController alloc] init]; 
    localNavigationController = [[UINavigationController alloc] initWithRootViewController:subviewController0]; 
    [localViewControllerArray addObject:localNavigationController]; 
    [subviewController0 release]; 
    [localNavigationController release]; 

    SubViewController *subviewController1 = [[SubViewController alloc] init]; 
    localNavigationController = [[UINavigationController alloc] initWithRootViewController:subviewController1]; 
    [localViewControllerArray addObject:localNavigationController]; 
    [subviewController1 release]; 

    [localNavigationController release]; 

    RootController.viewControllers = localViewControllerArray; 
    [localViewControllerArray release]; 

    [self.window addSubview:tabBarController.view]; 
    [self.window makeKeyAndVisible];
