    <p>Setting the accessory view needs to happen <em>inside</em> the <code>tableView:cellForRowAtIndexPath:</code> method. When you want to change the accessories from outside, the outside method needs to change the model first to indicate that check marks must be placed in certain cells, and then call <code>reloadData</code> on the <code>UITableView</code>.</p> <p>One way to store what cells are checked is an array of <code>NSIndexSet</code> objects - one index set per section. In the example below I show code for a single section, but you should get an idea of how to make multiple sections work.</p> <pre><code>// This variable needs to be declared in a place where your data source can get it NSMutableIndexSet *selected; // You need to initialize it in the designated initializer, like this: selected = [[NSMutableIndexSet alloc] init]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } if ([selected containsIndex:indexPath.row]) { [cell setAccessoryType:UITableViewCellAccessoryCheckmark]; } else { [cell setAccessoryType:UITableViewCellAccessoryNone]; } // Do the rest of your code return cell; } </code></pre> <p>Now in the code where you want to set rows selected or unselected you just need to call <code>[selected addIndex:rowToSelect]</code> or <code>[selected removeIndex:rowToUnselect]</code>, and call your table's <code>reloadData</code>.</p>

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.
