self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil]; 
navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController]; 
[self.window addSubview:[navigationController view]]; 
self.window.rootViewController = self.viewController; 
[self.window makeKeyAndVisible];

檢查這在您的應用程序添加UINavigationController：

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

    // start of your application:didFinishLaunchingWithOptions 
    // ... 

    viewController = [[ViewController alloc]init]; 

    UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:viewController]; 
    [self.window setRootViewController:navigationController]; 
    [window makeKeyAndVisible]; 

    [viewController release]; 
    [navigationController release]; 

    return YES; 
}
