我正在開發一個ipad應用程序，因爲我將應用程序縱橫比設置爲橫向並自動指向應用程序描述符xml中的true，如下所示：如何在加載啓動畫面時停止Ipad屏幕方向？ - 在Flex移動應用程序
<!-- The initial aspect ratio of the app when launched (either "portrait" or "landscape"). Optional. Mobile only. Default is the natural orientation of the device -->
<aspectRatio>portrait</aspectRatio>
<autoOrients>false</autoOrients>
默認情況下，我的應用程序在橫向視圖中加載，但是當用戶在「Landscape_Left」視圖中持有ipad時，即面向用戶的左手側的ipad-home-button，則啓動屏幕旋轉至「Landscape_right」上下翻轉。然後，用戶必須旋轉iPad 180度才能以直觀的視角查看應用，每次打開應用時都會發生這種情況。我無法阻止應用程序旋轉到默認的橫向視圖，我試圖在預初始化時將方向設置爲ROTATED_LEFT，但其旋轉到默認然後是左。

有沒有解決這個問題？它甚至在調用Application構造函數之前旋轉。
