MagicalRecord在静态库加载数据模型

我试图在静态库中使用MagicalRecord与数据模型。
当我调用

I'm trying to use MagicalRecord with a data model in a static library. When I just call

[MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:@"db.sqlite"];

在库中，似乎没有加载数据模型。调用

in the library, it doesn't seem to load the data model. A call to

[TheObject MR_createEntity];

会抛出异常：

could not locate an entity named 'TheObject' in this model.'

如何加载我想要使用的模型？
项目布局概述：

How do I load the model I want to use? An overview of the project layout:

我试图默认从主包中加载模型？

I figure MR tries to load the model from the main bundle by default?

[MagicalRecord setDefaultModelNamed:@"TheModel.xcdatamodeld"];

也不会找到它。
如果我尝试将库的模型资源文件复制到主项目，Xcode会崩溃。

will also not find it. And if I try to copy the library's model resource file into the main project, Xcode complains by crashing.
