    <p>I've created a feature in my app that loads a custom cell when tapping the cell. tapping the cell will show the extra buttons and tapping again will hide it, no problem with that. however, I think I have a cell reuse issue here when tapping rows next to the currently selected row. look at the screenshot, I tap North California then the buttons show up, when I tap Ethiopia the result is the second screenshot.</p> <p><a href="http://i228.photobucket.com/albums/ee262/romano2717/reuse.jpg" rel="nofollow">http://i228.photobucket.com/albums/ee262/romano2717/reuse.jpg</a></p> <p>here's the code</p> <pre><code> if(selectedIndexPath != nil &amp;&amp; [selectedIndexPath isEqual:indexPath]) { selectedIndex = indexPath.row; NSLog(@"selectedIndex %d",selectedIndex); static NSString *CustomCellIdentifier = @"CustomCell"; CustomCell *customCell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (customCell == nil) { customCell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CustomCellIdentifier] autorelease]; } customCell.locationLabelOutlet.text = [usgsFeeds objectAtIndex:[indexPath row]]; customCell.dateLabelOutlet.text = [pubDateArr objectAtIndex:[indexPath row]]; float thisMag; thisMag = [(NSNumber *)[magnitudeArr objectAtIndex:[indexPath row]] floatValue]; customCell.magnitudeImageOutlet.image = [self imageForMagnitude:thisMag]; [customCell setSelectionStyle:UITableViewCellSelectionStyleNone]; return customCell; } else{ static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; [cell setSelectionStyle:UITableViewCellSelectionStyleNone]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; locationLabel = [[[UILabel alloc] initWithFrame:CGRectMake(10, 3, 225, 20)] autorelease]; locationLabel.tag = kLocationLabelTag; locationLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:14.0]; locationLabel.backgroundColor = [UIColor clearColor]; [cell.contentView addSubview:locationLabel]; //same as above will follow } else{ locationLabel = (UILabel *)[cell.contentView viewWithTag:kLocationLabelTag]; dateLabel = (UILabel *)[cell.contentView viewWithTag:kDateLabelTag]; magnitudeImage = (UIImageView *)[cell.contentView viewWithTag:kMagnitudeImgTag]; } locationLabel.text = [usgsFeeds objectAtIndex:[indexPath row]]; dateLabel.text = [pubDateArr objectAtIndex:[indexPath row]]; float thisMag; thisMag = [(NSNumber *)[magnitudeArr objectAtIndex:[indexPath row]] floatValue]; magnitudeImage.image = [self imageForMagnitude:thisMag]; return cell; } </code></pre> <p>and this is my custom cell</p> <pre><code> - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier: (NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; if (self) { locationLabelOutlet = [[UILabel alloc] initWithFrame:CGRectMake(10, 3, 210, 17)]; locationLabelOutlet.font = [UIFont fontWithName:@"Helvetica-Bold" size:14.0]; locationLabelOutlet.backgroundColor = [UIColor clearColor]; //and other outlets [thisContainer addSubview:locationLabelOutlet]; [thisContainer addSubview:magnitudeImageOutlet]; [thisContainer addSubview:dateLabelOutlet]; [buttonsView addSubview:locButton]; [buttonsView addSubview:detButton]; [buttonsView addSubview:shabutton]; [buttonsView addSubview:favButton]; [thisContainer addSubview:buttonsView]; [self.contentView addSubview:thisContainer]; </code></pre> <p>this is for the did select</p> <pre><code> - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:NO]; selectedIndexPath = indexPath; if(selectedIndex == indexPath.row) { selectedIndexPath = nil; [tableView reloadRowsAtIndexPaths: [NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; selectedIndex = -1; return; } if(selectedIndexPath != nil &amp;&amp; [selectedIndexPath isEqual:indexPath]) { [tableView reloadRowsAtIndexPaths: [NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } } </code></pre>

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.
