更改ViewController的名称会导致应用程序崩溃？

我使用iOS SDK 4.3在XCode（4.0）中创建了一个新的基于View的iPhone应用程序。然后我将ViewController的名称从MyProjectNameViewController更改为LoginViewController。我还用LoginViewController代替了我能找到的MyProjectNameViewController的每个实例，并且我已经仔细检查了界面构建器中的所有链接。更改ViewController的名称会导致应用程序崩溃？

然而，当我尝试运行应用程序，它崩溃了：

什么我需要做的，解决这一问题？

说真的，我一遍又一遍地检查了每一个类，并查看了xibs的源代码，并且没有一个旧的控制器名称的实例。 – DanielGibbs

您是通过手动还是使用重构工具来完成此操作？ – Abizern
