object - Merging NSManagedObjectContexts - Get Reference to NSManagedObjects in the merged context? -

-

i have main context create nsmanagedobject's on if said object doesn't have required fields. however, if want create nsmanagedobject subclass have required fields, copy main managed object context , create object (that has required fields) on new context. once required fields object have been populated, merge duplicate context main context. issue references had objects required fields still on old context after merge? there option somewhere "after merge switch object references newly-created counterpart in merged context"? reason after merge contexts, want start setting them related objects each other, error saying can't objects in separate contexts. error makes sense, confused how may switch nsmanagedobject subclass's reference new 1 in main (merged) context.
