greetings!
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.
suppose I have 3 enties:
"box" which has a property "storyMapId"
"map" which has properties "mapId" and "storyId"
"story" which has property "storyId2"
box.storyMapId has a 1-1 relationship with map.mapId
map.storyId has a 1-many relationship with story.storyId2
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?
thanks,
