Question

if i delete an cd entity and than save the mod

[self.moc deleteObject:(NSManagedObject *)someCDEntity];

[self saveMoc];

the pointers to this cd entity will become faults

by trying accessing the fault or ask for isDeleted, i get a

'CoreData could not fulfill a fault for

the problem is, as soon as i save the mod, the isDeleted doesn’t work any more

so how can i detect if an entity is removed? because just asking for isFault, doesn’t indicate that it was deleted… and i cannot use isDeleted

Answer 1

i found help in this OSX oriented thread

How can I tell whether an `NSManagedObject` has been deleted?

- (BOOL) entityWasDeleted:(SomeEntity *)someEntity {

    return ((someEntity == nil) || ([self.moc existingObjectWithID:someEntity.objectID error:NULL] == nil));
}

Beware : don’t use the code bellow, as it might not always work

if (managedObject.managedObjectContext == nil) {
    // Assume that the managed object has been deleted = might not always work
}
