Posted whenever a managed object context completes a save operation.
The notification object is the managed object context. The userInfo dictionary contains the following keys: NSInsertedObjectsKey, NSUpdatedObjectsKey, and NSDeletedObjectsKey.
You can only use the managed objects in this notification on the same thread on which it was posted.
You can pass the notification object to mergeChangesFromContextDidSaveNotification: on another thread, however you must not use the managed object in the user info dictionary directly on another thread. For more details, see “Concurrency with Core Data”.
