When I need to know whether or not a managed object is deleted, often I fall into the trap of trying -[NSManagedObject isDeleted], forgetting that its documentation states …
"… It may return NO at other times, particularly after the object has been deleted. …"
In other words, they should have named that method -isDeletedForSure, to indicate that the NO result is not reliable.
Anyhow, today I fixed a problem by using this instead …
BOOL isDeleted ;
isDeleted = [object isDeleted] || ([object managedObjectContext] == nil) ;
I'm not sure if it will work in all situations. I suppose that sending the magical -processPendingChanges would be another workaround.
