How do I reload a NSFetchedResultsController?

Question

I have an app that preloads a months worth of data and it gets released a day at a time.

NSDate *now = [NSDate date];

      // Create predicate

      NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(location.name == %@) AND (date < %@)",longLocation,now];

Everything worked great before multi-tasking, but now that it no longer starts from nil I cannot get it to recognize the new date and reload the data based on that new date.

I have the view loaded into a TabBarController. It seems to want to hang onto that view forever and I can't seem to get viewWillAppear to do anything.

Any help would be greatly appreciated. Thanks

I Tried

[self.fetchedResultsController performFetch:&error];

But it's not loading the revised date
