managedobjectcontext

PROBLEM STATEMENT When attempting to save a record to a read/write store that is one of two SQLite stores assigned to the same PersistentStoreCoordinator, my iPhone app crashes. One obvious issue when saving a record is the PersistentStoreCoordinator does not know in which Store to save the data (only because I don't know how to make this happen). First I will provide the big picture to make sure my approach is sound. Then I will supply the implementation details. BACKGROUND This is a simplified example representing the key aspects of the actual app I am working on. Seed Data User Input

I am slightly confused about parent/child contexts for ManagedObjectContext . When I setup a child context and set the parent context, does the child context contain all the objects of the parent context? I am using the stock Core Data methods that get created in the AppDelegate , but I changed the ConcurrencyQueue to main. In my method that is supposed to update the db: Create child context, set parent context Perform block on child context Fetch from parent context Create or update object in child context Call save on child context Have Notification listener to handle child context saves
