Question

我想将Aviary SDK Objective-C库集成到Monotouch项目中。我使用'Monotouch Binding Project'模板。我已经构建了DLL（感谢聪明的人！）该项目是在模拟器上编译和运行的。

但是我无法显示主要的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：

似乎此错误（无法创建具有nil模型的NSPersistentStoreCoordinator ）与资源包链接，Aviary SDK需要添加。

来自Aviary iOS Setup Guide：

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）
TestAviary

谢谢！

每Jonathan.Peppers条评论：

将大多数此类文件添加到Build Action Content的项目中将解决此问题。

可能的捆绑问题 - 无法使用nil模型创建NSPersistentStoreCoordinator
