Question

Answer 1

You can scroll your table view to that cell and you can specify that you want to scroll it on top when you select the cell:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

Hope this is what you are after.
