Remco,
What you can do is subclass NSManagedObject for that entity (if you haven't
already done that) and add the -didSave method:
- (void)didSave
{
if ([self isDeleted])
[self _removeFile];
[super didSave];
}
Kind regards,

Hi,
I've a Core Data app where instances of a particular entity contain a
filename. When these instances are removed from the object graph I
also want to remove the file. But in order to support undo
management, I can't directly remove the file, I've to wait until the
managed object context is send a save: message. Now I've the problem
that at that time I can only request the objects that will be deleted
from the persistent store, not the objects that haven't been saved
yet. How do I get a list of all objects that are deleted? The unod
manager also doesn't seem to be able to give me a list of deleted
objects.
Thanks in advance,
Remco Poelstra
