title: shouldAutoRotate not working in swift
body: <p>I know if VC has <code>navigationController</code> it should contain some like <a href="https://stackoverflow.com/a/12790798/1146533">this</a>. But what about swift? How to able call <code>shouldAutoRotate</code> in VC with <code>navigationController</code>? My <code>navigationController</code>s has standard class <code>UINavigationController</code> (not custom). I want make <code>shouldAutoRotate</code> false for all my VC except single. As I understood there no another ways to just use "Portrait" and make available to rotate single VC</p>
