When a customized UITableViewCell is queued (e.g. it goes off the screen) how much of it's setup is retained? For example:

1. Are any views added to it previously remain in place (eg [cell.contentView addSubview:someUILabel]; )
2. The configuration of such subviews? (e.g. fonts)
3. Data from such subviews?

Just trying to understand when I do dequeueReusableCellWithIdentifier and get a cell from the queue, how re-work, if any, do I need beyond changing the data (e.g. like changing the text values in the UILabels subviews).
