    <p>I want to make a UITableView act like an accordion. When a row is tapped it should insert a special row right below the tapped row and then remove any other special row from previous taps. I have tried many things but the code below is my latest attempt.</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSIndexPath *removeIndex; for (int i = 0; i &lt; [players count]; i++) { NSString *player = [players objectAtIndex:i]; if ([player isEqualToString:@"ADJUST_SCORE_ROW"]) { removeIndex = [NSIndexPath indexPathForRow:i inSection:indexPath.section]; [players replaceObjectAtIndex:i withObject:@"DELETE_ME"]; break; } } [scoreTableView beginUpdates]; NSIndexPath *insertPath; if (removeIndex &amp;&amp; [removeIndex row] &lt; indexPath.row) { insertPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section]; } else { insertPath = [NSIndexPath indexPathForRow:indexPath.row + 1 inSection:indexPath.section]; } [players insertObject:@"ADJUST_SCORE_ROW" atIndex:insertPath.row]; [scoreTableView insertRowsAtIndexPaths:[NSArray arrayWithObject:insertPath] withRowAnimation:UITableViewRowAnimationTop]; for (int i = 0; i &lt; [players count]; i++) { NSString *player = [players objectAtIndex:i]; if ([player isEqualToString:@"DELETE_ME"]) { [players removeObject:player]; break; } } if (removeIndex) { [scoreTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:removeIndex] withRowAnimation:UITableViewRowAnimationTop]; } [scoreTableView endUpdates]; } </code></pre>

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.
