UITableViewCell + standard disclosure indicator + secondary UIButton + HIG violation

I've a simple question but I cannot find a clear answer around the web.

Suppose I have a custom

UITa开发者_StackOverflow社区bleViewCell

With the default disclosure detail button that take to a detail view controller.

Is it good to have secondary, custom button that, when tapped, fires another action rather than presenting the detail view controller?

Or it could be an HIG violation?

any suggestion very appreciated.

Where would you like to put another button? Maybe the simplest thing to do is put the other action in

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

I probably mis-explained.
