DCTCoreDataStack

DCTCoreDataStack is intended for non-document based apps, and sets up the whole Core Data structure such that after initializing, the managedObjectContext property is ready for use.

DCTCoreDataStack provides the following features:

1. An encapsulation of the complete Core Data stack of NSManagedObjectContext, NSPersistentStoreCoordinator, NSPersistentStore, and NSManagedObjectModel
2. On supporting OS’s, writing to disk is performed on a background thread, by using a parent context. Saving the main context automatically triggers saving the parent context asynchronously
3. -[NSManagedObjectContext dct_saveWithCompletionHandler:] method can be used to be notified when saving to disk finishes, asynchronously if possible
4. Allows you to resolve errors when loading the persistent store by setting the didResolvePersistentStoreErrorHandler block and handling the error
5. On iOS, the app entering the background, or terminating, automatically triggers a save if needed. You can be notified of such saves by setting the automaticSaveCompletionHandler block
6. On iOS, when saving on a background thread, the stack protects against termination/suspension by declaring the save as a background task
7. Providing YES for DCTCoreDataStackExcludeFromBackupStoreOption in the storeOptions will exclude the persistent store from being backed up

Thanks

Thanks to Mike Abdullah for persisting on making this better (via continuously pestering me) and writing a lot of the documentation.
