Which methods are good to overwrite when creating custom NSManagedObject subclasses?

Question

The Core Data Programming Guide talks a lot about what not to overwrite. So the question is: What is good to overwrite?

Like I see it, I can't overwrite -init or -initWithEntity:insertIntoManagedObjectContext:

So where else would be a good overwrite point to set up some basic stuff? Or is it generally not needed to do custom initialization? Does the whole thing rely only on accessing properties which then start to do fancy things? So no custom initializations?

Answer 1

I often override the following methods:

-(void) awakeFromFetch
-(void) awakeFromInsert
-(void) willTurnIntoFault
-(void) didTurnIntoFault

Don't forget to call super implementations. In Addition the following method should be overridden to process Objects after undo/redo

- (void)awakeFromSnapshotEvents:(NSSnapshotEventType)flags
