NSPredicate and NOT IN and array

Subject: NSPredicate and NOT IN and array

I would like to get an array of items that are NOT IN and array. Is there a way to do this with a NSPredicate

Example:

NSArray *listOfIDs = [self getSomeIDs]; NSFetchRequest *fetchRequest = [[[NSFetchRequest alloc] init] autorelease]; [fetchRequest setEntity: [NSEntityDescription entityForName:@"items" inManagedObjectContext:myMOC ] ]; [fetchRequest setPredicate: [NSPredicate predicateWithFormat: @"(id NOT IN %@)", listOfIDs]]; Any ideas would be great.

thanks
-dave
