我想知道如何將NavigationController樣式的應用程序轉換爲TabBarcontroller樣式的應用程序。我改變了我的主窗口不包含navigationcontroller了(但不是tabbarcontroller)和我的代表也恰如其分,但是當我啓動應用程序的東西仍然認爲我想要一個navigationController:將導航欄轉換爲TabBar應用程序
終止應用程序由於未捕獲的異常「NSUnknownKeyException ',原因:'[setValue:forUndefinedKey:]:這個類不是關鍵的導航控制器編碼兼容的值。'

我委託的界面如下:
@interface CPPlayerAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
UIWindow *window;
UITabBarController *tabBarController;
}
#pragma mark -
#pragma mark Window/view
@property (retain) IBOutlet UIWindow *window;
@property (retain) IBOutlet UITabBarController *tabBarController;
我委託的實現:
@implementation CPPlayerAppDelegate
@synthesize window;
@synthesize tabBarController;
@synthesize stateController, distribution, languageManager, updateParser, soundPlayer, ticketProcessor;
#pragma mark -
#pragma mark Application lifecycle
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[window addSubview: tabBarController.view];
[window makeKeyAndVisible];
}
我在哪裏可以指定應用程序是一個tabbarcontrolled應用程序,而不是navigationbarcontro lled應用程序?
在此先感謝,
