Adding a bit to Marco's answer:

First, if you're using multiple selection, you can add this method to your ViewController and call it whenever you need to call [tableView reloadData]:

- (void)reloadTableView
{
    NSArray *indexPaths = [self.tableView indexPathsForSelectedRows];
    [self.tableView reloadData];
    for (NSIndexPath *path in indexPaths) {
        [self.tableView selectRowAtIndexPath:path animated:NO scrollPosition:UITableViewScrollPositionNone];
    }
}

Second, if you're in a UITableViewController and you want to preserve selection after tableView appears there's a feature in UITableViewController: clearsSelectionOnViewWillAppear you can turn on or off.
