title: iOS9 does not load insecure resources from a secure page (SSL/HTTPS)
body: <p>I am trying to load a page into UIWebView on iOS9 using https:// URL. The page loaded includes CSS and images from an insecure server.</p>
  
  <p>E.g. the page loaded: <em><strong>https</strong>://www.example.com/</em> which includes stylesheet <em><strong>http</strong>://www.example.com/style.css</em> and image <em><strong>http</strong>://www.example.com/image.jpg</em></p>
  
  <p>Everything works if the original page is loaded via insecure connection (regular http). Everything works also on iOS8 both via HTTPS and HTTP.</p>
  
  <p>I did set <em>NSAppTransportSecurity</em> to <em>NSAllowsArbitraryLoads</em> in application PLIST file:</p>
  
  <pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
  &lt;dict&gt;
      &lt;key&gt;NSAllowsArbitraryLoads&lt;/key&gt;
      &lt;true/&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>Though when loading the page via HTTPS, the images are loaded OK, but CSS files are not. Seems like <em>UIWebView</em> blocks loading insecure resources from a secure page.</p>
  
  <p>Is there any setting of <em>UIWebView</em> that will allow to load CSS via insecure connection?</p>
