    <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>

    1. COThe problem (I think) is that the fetch request is used only for the initial fetch, but not for the change tracking of the FRC.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
