如何使用UITabBarController解決iOS 6中的方向問題？

在我的應用程序中，我有一個橫向視圖控制器應該在設備處於橫向模式時被調用，這很好。但問題是，當我旋轉回肖像時，它變得混亂起來。我在我的應用程序委託這樣做：如何使用UITabBarController解決iOS 6中的方向問題？

    // Override point for customization after application launch. 
    UIViewController *viewController1, *viewController2, *viewController3, *viewController4, *viewController5; 

    UIImage * logoImage = [UIImage imageNamed:NAVIGATION_LOGO_IMAGE];

    self.navController.navigationItem.titleView.frame = CGRectMake(340,0 , 450, 55); 

    // Create initialized instance of UITabBarController

嘗試子類的UITabBarController和實施新的iOS在該子類6旋轉委託方法。然後使用該子類作爲您的根視圖控制器爲更好的旋轉控制的iOS 6

下在你的標籤欄控制器的子類指定：

- (NSUInteger)supportedInterfaceOrientations{ 
    return UIInterfaceOrientationMaskLandscape; 
}

另一種選擇是放置在這一個導航控制器子類，然後在導航控制器中嵌入特定於景觀的視圖控制器。
