title: Limit results of NSFetchedResultsController in UITableView
body: <p>This will probably seem silly, but I cannot figure out how too set the limit of a NSFetchedResultsController. Even when setting the fetchLimit I still get all records. I want to set the limit to 1 so that in "freemium" mode there is only one option, but when the app is unlocked you get the full table</p>
  
  
  
  <pre class="lang-objective-c prettyprint-override"><code>NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"Poem"];
  fetchRequest.returnsObjectsAsFaults = NO;
  fetchRequest.resultType = NSManagedObjectResultType;
  fetchRequest.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"createdAt" ascending:NO selector:nil]];
  fetchRequest.fetchLimit = 1;
  // setup my predicate
  _fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:kDataContext sectionNameKeyPath:nil cacheName:nil];
  _fetchedResultsController.delegate = self;
  </code></pre>
  
  <p>I also have a method to fetch data. This method is intended to be run at load and when the user unlocks the full version of the app.</p>
  
  <pre class="lang-objective-c prettyprint-override"><code>- (void)refetchData {
      NSError *error = nil;
      [_fetchedResultsController performFetch:&amp;error];
      // handle error
  
      [self.documentsTable reloadData];
  }
  </code></pre>
  
  <p>I've experimented with setting the UITableView numberOfRowsInSection to return 1, but then I get warning logs. Plus, I feel that is cheating. I'd like to keep the app data-driven.</p>
  
  <p>edit:
  I might also add that I'm using AFIncrementalStore to sync my data with a web service. I'm not sure if this would cause any problems.</p>
