我正在開發一款適用於iPad的遊戲,並使用菜單屏幕啓動它。有一段時間,菜單屏幕會在模擬器中出現。我使用的是xcode在啓動基於視圖的應用程序時提供的主視圖控制器。但不幸的是,我不小心切斷了界面生成器中UIView和視圖控制器之間的連接,重新連接後,屏幕現在變成空白。當我在界面生成器中模擬屏幕時,它工作正常,但在xcode中運行時沒有問題。下面是視圖控制器代碼:模擬器中的空白屏幕問題

我真的沒有在這裏看到的任何問題,所以我假設它是與我重新連接視圖控制器的視圖。我沒有我正在使用的實際視圖文件,只是視圖控制器。任何人都可以幫忙嗎?
好的,我檢查了這個位置,主要的筆尖文件的基本名稱是MainWindow。我沒有弄錯窗口,只是視圖控制器的視圖。嘗試更改文件基本名稱只會導致崩潰。 – RaysonK 2011-05-25 22:28:43
我做了一個項目的確切副本,並再次嘗試,現在它工作正常。這可能是你說的信息文件中的一些東西。謝謝您的幫助! – RaysonK 2011-05-25 22:50:39
