MonoMac：和 Xcode 4.0 错误：“Interface Builder 文件中的未知窗口类 MainWindow”
我创建了一个新的 MonoMac 项目，并使用 Interface Builder (Xcode) 打开 MainWindow.xib。进行简单的更改（重命名为窗口标题）后，项目无法再构建。 有谁知道如何解决这个问题？
我在 OS X 10.6.7 上使用 MonoDevelop 2.6、MonoFramework-2.10.1 和 Xcode 4.0。
这是错误消息：
2011-03-28 18:45:39.986 HelloWorld[30332:613] Interface Builder 文件中的未知窗口类 MainWindow， 创建通用窗口来代替
未处理的异常：System.InvalidCastException：无法从源类型转换为目标类型。 在HelloWorld.MainWindowController.get_Window() <0x0002e>; 在 HelloWorld.AppDelegate.FinishedLaunching (MonoMac.Foundation.NSObject) <0x0003d> 处 在（包装动态方法）对象。[HelloWorld.AppDelegate.Void FinishedLaunching（MonoMac.Foundation.NSObject）]（MonoMac.Foundation.NSObject，MonoMac.ObjCRuntime.Selector，MonoMac.Foundation.NSObject）<0x00033> 在（包装本机到托管）对象。[HelloWorld.AppDelegate.Void FinishedLaunching(MonoMac.Foundation.NSObject)] (MonoMac.Foundation.NSObject,MonoMac.ObjCRuntime.Selector,MonoMac.Foundation.NSObject) <0x000eb> at (包装器托管到本机) MonoMac.AppKit.NSApplication.NSApplicationMain (int,string[]) <0x00003>; 在 MonoMac.AppKit.NSApplication.Main (string[]) <0x00017> 在 HelloWorld.MainClass.Main (string[]) <0x00019>
感谢您的任何帮助。
干杯
PS：我在 http://monotouch.net/Documentation/Troubleshoot#Unknown_class_XXXX_in_Interface_Builder_filebut 上找到了故障排除帮助，我想它不会在这种情况下不算数，因为默认情况下类 MainWindow 已经存在。
I've created a new MonoMac project and opened the MainWindow.xib with Interface Builder (Xcode). After doing a simple change (renamed Window title), the project can't be built anymore.
Does anyone know how to fix this?
I'm using MonoDevelop 2.6, MonoFramework-2.10.1 with Xcode 4.0 on OS X 10.6.7.
This is the error message:

Thanks for any help.
Cheers
PS: I found a troubleshooting help on http://monotouch.net/Documentation/Troubleshoot#Unknown_class_XXXX_in_Interface_Builder_filebut I guess it doesn't count in this case, since the class MainWindow already exists by default..

Xcode 4.0 is not really supported right now.. but I hope someone else corrects me :-)
这篇文章包含有关不完整支持的说明Xcode 4.0。建议使用 Xcode 3.2.6，直到支持 Xcode 4.0。
This post contains the explanation about the incomplete support of Xcode 4.0. It is recommended to use Xcode 3.2.6 until Xcode 4.0 is supported.
