Don't forget to save the Context after you have deleted a NSManagedObject. So here is the general code;

NSManagedObjectContext * context = [self managedObjectContext];
[context deleteObject:objectToDelete];

NSError * error = nil;
if (![context save:&error])
{
    NSLog(@"Error ! %@", error);
}

In your case it should have the snippet after the for loop.

for (NSManagedObject *managedObject in array) {
    [moc2 deleteObject:managedObject];
}
NSError * error = nil;
if (![context save:&error])
{
    NSLog(@"Error ! %@", error);
}
