MonoTouch 解决方案包括两个项目。

  • MonoTouch Binding Project：链接原生 ObjC 库的 API 合约接口
  • 测试客户端应用程序

本机 ObjC 库需要包含核心数据模型文件 (.momd)。我已将其添加到 Test App 的项目中。

但是应用程序崩溃并出现以下错误：

    Unhandled Exception: MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: Cannot create an NSPersistentStoreCoordinator with a nil model

如何将此所需的 CoreData 模型文件添加到测试应用程序中，以便对本机库可见？

谢谢！

根据我的评论：

Build Action使用of将大多数这样的文件添加到您的项目Content中将解决该问题。
