title: iOS9 App Transport Security blocked web service with plist modified
body: <p>Run my app on iOS 9 device,
  got error logged:</p>
  
  <blockquote>
    <p>App Transport Security has blocked a cleartext HTTP (http://) resource
    load since it is insecure.  Temporary exceptions can be configured via
    your app's Info.plist file.</p>
  </blockquote>
  
  <p>I surely did add <code>NSAllowsArbitraryLoads</code> to info.plist:</p>

  <p>It still loaded nothing from the web...
  What did I miss?</p>
  
  <p>Do I have to allow the certain domain for my web service ?</p>
