更改ViewController的名稱會導致應用程序崩潰？

我使用iOS SDK 4.3在XCode（4.0）中創建了一個新的基於View的iPhone應用程序。然後我將ViewController的名稱從MyProjectNameViewController更改爲LoginViewController。我還用LoginViewController代替了我能找到的MyProjectNameViewController的每個實例，並且我已經仔細檢查了界面構建器中的所有鏈接。更改ViewController的名稱會導致應用程序崩潰？

然而，當我嘗試運行應用程序，它崩潰了：

什麼我需要做的，解決這一問題？

說真的，我一遍又一遍地檢查了每一個類，並查看了xibs的源代碼，並且沒有一箇舊的控制器名稱的實例。 – DanielGibbs
