Well, as I mentioned I have stuck with KVO. I don't see why you need
to remove observers when turning into a fault. You only need to
remove observers before the object disappears.
Ah, good point. I was using -didTurnIntoFault since -[NSManagedObject
dealloc] is unreliable and not recommended for overriding.
I have created my own NSManagedObject subclass as you have, and I
have a
-removeSelfFromObserveredObjects method in that subclass that I call
before deallocating the MOC. (Fetch all objects from MOC and call
this method, if it exists.) ...it's not pretty, but it works.
Note that a fetch will not return deleted objects that might still
be on the undo stack, so I also call removeSelfFromObserveredObjects
from the managed object's dealloc method.
Oooo, dealloc is not recommended for overriding.
(You will have to check that you do not call
removeSelfFromObserveredObjects twice.) As I said, it's not pretty,
but it works.
Wow, that ^is^ ugly. I'll think about it.
If anyone has a better way, I'd love to hear it!
Ditto from me.
Thanks, Dave.
