Re: CoreData fetched property: one-to-one-to-many relationship

[Omar Qazi]

Create an NSFetechedPropertyDescription by setting up a fetch request in code, then add the property using the setProperties method of NSEntityDescription. It is only possible to edit an NSEntityDescription if you are not associated with a persistent store coordinator, so be careful. You might want to just add a custom method to the class of your Core Data model to execute the fetch request and get the job done.

I'm trying to figure out how to dynamically (in code) set up a fetched property with a Coredata in-memory store. The documentation is not detailed enough for me to quite see what the correct way to set the code up is and I'm not finding much in the way of useful sample code when searching on NSFetchedPropertyDescription. What is the correct way to programmatically add a fetched property to the box to get the list of stories for a given box managed object?
