標籤欄視圖不會加載

Question

在我的應用程序委託接口我：

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

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

實施

，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; 
} 

在我的主要廈門國際銀行窗口，我有一個標籤欄控制器，該控制器以rootController身份連接到應用程序委託。 當我運行該程序時，窗口顯示，但標籤欄視圖不會被加載。 感謝任何幫助。謝謝。

你在xib的RootController中有一個subViewController嗎？如果你不是，它的代碼如下。

UITabBarController應該有一個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];
