我想将Aviary SDK Objective-C 库集成到 Monotouch 项目中。我为此使用“Monotouch Binding Project”模板。我已经构建了 DLL（感谢聪明人！）该项目在模拟器上编译并运行。
但是我无法显示主 Aviary 视图和以下代码
this.afPhotoEditor = new AFPhotoEditorController(UIImage.FromFile("Images/site.jpg"));
AFDelegate afDelegate = new AFDelegate(this);
this.afPhotoEditor.Delegate = afDelegate;
this.PresentModalViewController(this.afPhotoEditor, true);
返回错误：

这个错误（Cannot create an NSPersistentStoreCoordinator with a nil model）似乎与 Aviary SDK 需要添加的资源包相关联。
4. Copy resources Make sure AviarySDKResources.bundle is included in your target's "Copy Bundle Resources" build phase.
所以我通过 MonoDevelop 中的“添加现有文件夹..”菜单项添加了这个包。

它包括2个项目：
- AviaryBinding（MonoTouch 绑定项目）
- 测试鸟舍
谢谢！
