- encapsulating all core data stack in one class
- multithreaded managed object context without pain (if you don't do any massive imports you don't even have to think about multiple contexts, use one for everything and we will do background saves for you)
- easily create new (temporary) private child managed object context for massive imports (reference: Marcus Zarra Core Data Stack)
- added protocol to mark all classes that should use SSPersistenceController (I encourage doing it by property injecting and not using AppDelegate as an access to all globally used methods - I did that as well before)
- NSManagedObject category:
+ (NSString *)entityClassName(so you won't use it as a string - it's bad)
- NSManagedObjectContext category (CRUD helper methods):
- (NSArray *)fetchAllEntities:(Class)entityClass
withPredicate:(NSPredicate *)predicate
withSorting:(NSSortDescriptor *)sort
fetchLimit:(NSUInteger)limit
prefetchRelations:(NSArray *)prefetchRelations
fetchProperties:(NSArray *)properties;
- (NSManagedObject *)fetchEntity:(Class)entityClass
withPredicate:(NSPredicate *)predicate
prefetchRelations:(NSArray *)prefetchRelations;
- (NSInteger)countAllEntities:(Class)entityClass withPredicate:(NSPredicate *)predicate;
- (NSManagedObject *)insertNewObject:(Class)entityClass;
