How to set a header and render a twig template without renderView() method in symfony2.X controller

Question

How would one go about setting a header (Content Type) and rendering a twig template without renderView() method in symfony2.X controller?

I'm not sure if the accepted answer is valid anymore, or if ever was. Anyhow, here's a couple ways of doing it. I've got an XML, and JSON sample for you here.

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\JsonResponse;

class DefaultController extends Controller{
  public function indexAction($x = 0)
  {
    $response = new Response(
      $this->renderView('AcmeMyBundle:Default:index.html.twig', array('x'=>$x)),
      200
    );
    $response->headers->set('Content-Type', 'text/xml');

    return $response;
  }

  //...

or for JSON response

//...

public function indexAction( $x = 0 )
{
  $response = new JsonResponse(
    array('x'=>$x)
  );

  return $response;
}
