ios - UITableViewCell Set selected initially

Hi there I have situation where in an iPad app my master controller has list and details controller have its details , a typical UISplitViewController pattern. What I want to achieve is , my first row should be initially selected and later I want to give selection choice to user. I am using cell's setSelected and in didSelectRowAtIndexPath method removing selection like this.

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
    NSIndexPath* path = [NSIndexPath indexPathForRow:0 inSection:0];
    UITableViewCell* cell = [tableView cellForRowAtIndexPath:path];
    [cell setSelected:NO];
}

For the cell to appear selected, you have to call -setSelected:animated: from within -tableView:willDisplayCell:forRowAtIndexPath: like so:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (/* should be selected */) {
        [cell setSelected:YES animated:NO];
    }
}

Calling -setSelected from anywhere else has no effect.
