REAL-LIFE PROBLEM
In a managed memory application, I have a managed object which,
besides its Core Data managed properties, has a single instance
variable, a worker-kind of object which does some heavy lifting for
it. So that this retained worker, etc., will be deallocced, I need
this managed object to get deallocced when no longer needed.
The documentation [1] seems very clear that, although the
'insert...' methods return an autoreleased NSManagedObject, a
managed object may be retained by:
(a) the managed object context, until changes are saved
or rolled back, or,
(b) the managed object context's undo manager, as long as
an action involving the managed object remains on
the undo stack.
The documentation is also clear that Core Data "reserves exclusive
control over the life cycle of the managed object".
Absent a really good reason not to, you probably should release (and
nullify the iVar) the worker-kind object when you are turned into a
fault (-didTurnIntoFault.)
If you do this, does it solve your problem?
