title: How to find indexPath for tapped button in tableView Using Seque
body: <p>I have a <code>UITableView</code> using prototype cell.</p>
  
  <p>The cells have a <code>UIButton</code> that show a <code>UIViewController</code> (Modal) using <code>Segue</code>.</p>
  
  <p>My question is : How can i pass <code>IndexPath</code> of cell to second view controller</p>
  
  <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
  
      if ([segue.identifier isEqualToString:@"showGamerDetail"]) {
  
              //its not worked:
              NSIndexPath *indexPath = [self._tableView indexPathForSelectedRow];
              nDetailViewController *destinationViewController = segue.destinationViewController;
              destinationViewController.selectedRowTitle = [gamers objectAtIndex:indexPath.row];
  
          destinationViewController.indexPath = indexPath;
          destinationViewController.delegate = self;
      }
  </code></pre>
