    <p>I have a <code>UITableView</code> which uses 2 <code>NSFetchedResultsControllers</code>. Each <code>NSFetchedResultsController</code> has only one section. However, the table has 4 sections. I populate the 4th section of the table with the results of one of the <code>NSFetchedResultsControllers</code>. Everything works fine so far. But if the user deletes the first cell on the first section, the <code>NSFetchedResultsControllers</code> are changed. The rows in the last section of the table might be deleted. When this method is called:</p> <pre><code>- (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: NSLog(@"section: %d, row: %d", [newIndexPath section], [newIndexPath row]); [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; ... } </code></pre> <p>The section is always 0 because it's the section of the <code>NSFetchedResultsControllers</code>. Thus, the section doesn't match the correct one on the table view.</p> <p>Is there a workaround? I would basically like to change the section of a <code>NSFetchedResultsController</code> to 3 instead of 0.</p>

Guidance
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.
