How can I detect when a UITableViewCell derived object gets removed from a table and into the cache?
after ios 6.0 you have the following method of UITableViewDelegate
- (void)tableView:(UITableView *)tableView didEndDisplayingCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
Use this method to detect when a cell is removed from a table view, as opposed to monitoring the view itself to see when it appears or disappears.
