You are correct about renderView(), it's only a shortcut for Controllers. When using a service class and inject the templating service, all you have to do is change your function to render() instead. So instead of

return $this->renderView('Hello/index.html.twig', array('name' => $name));

you would use

return $this->render('Hello/index.html.twig', array('name' => $name));

Update from Olivia's response:

If you are getting circular reference errors, the only way around them is to inject the whole container. It's not considered best practice but it sometimes cannot be avoided. When I have to resort to this, I still set my class variables in the constructor so I can act as if they were injected directly. So I will do:

use Symfony\Component\DependencyInjection\ContainerInterface;

class MyClass()
{
    private $mailer;
    private $templating;

    public function __construct(ContainerInterface $container)
    {
        $this->mailer = $container->get('mailer');
        $this->templating = $container->get('templating');
    }
    // rest of class will use these services as if injected directly
}

Side note, I just tested my own standalone service in Symfony 2.5 and did not receive a circular reference by injecting the mailer and templating services directly.
