title: Is it possible to display a SFSafariViewController inside of a UITabBarController?
body: <p>I want to load <code>SFSafariViewController</code> inside of a tab, so the tab bar is at the bottom of the entire Safari view.</p>
  
  <p>Is this possible? I tried this with no luck:</p>
  
  <pre><code>[self.tabBarController presentViewController:sfController animated:YES completion:nil];
  </code></pre>
  
  <p>Is it <em>required</em> that the Safari view be full screen?</p>
