Global Variable


A notification of changes made to managed objects associated with this context.


NSString *const NSManagedObjectContextObjectsDidChangeNotification;


The notification is posted during processPendingChanges, after the changes have been processed, but before it is safe to call save: again (if you try, you will generate an infinite loop).

The notification object is the managed object context. The userInfo

dictionary contains the following keys: NSInsertedObjectsKey, NSUpdatedObjectsKey, and NSDeletedObjectsKey.

Note that this notification is posted only when managed objects are changed; it is not posted when managed objects are added to a context as the result of a fetch.
