Hi All,
I'm using core-data and need to know when a particular core-data
object (derived from NSManagedObject of course) is about to be
deleted. I'm deleting objects simply by using the managed object
context's deleteObject method, like this:
[[theObject managedObjectContext] deleteObject:theObject];
Is there a way to be notified immediately of the delete? I need to
know immediately, not only when the context is saved. Am I missing
something painfully obvious here?
now, I could of course put a 'deleteThisObject' method onto the class
I'm deleting, but isn't there a core-data way to handle this?
I've tried catching the
NSManagedObjectContextObjectsDidChangeNotification notification - but
that only fires on context saves, same with the willTurnIntoFault
method as well as the dealloc - all these methods are only ever called
when the context is being saved - which in my case is (a)
unpredictable, (b) too late .
Help / tips are greatly appreciated,
Thanks
