I use stackmob as backend and coredata.
I have "User" and "Sport" objects (User <<-> Sport). All users must have a sport object as require. If some user is logged in, others can't use this sport object until all users are logged out. For example, I want to change my sport. When I change it I have a crash. Because, sport have reverse relation to users. Seems I can't use same object between users. How it possible? And how to resolve this situation?
Crashed here(SMIncrementalStore.m):
- (id)newValueForRelationship:(NSRelationshipDescription *)relationship
forObjectWithID:(NSManagedObjectID *)objectID
withContext:(NSManagedObjectContext *)context
error:(NSError *__autoreleasing *)error
