title: react-native-image-viewer - Landscape View didn't work on IOS
body: <p>On Android, Landscape-Mode works like a charm, but on IOs I've found following issue:</p>
  
  <p>Mobile-Device is in Landscape-Mode:</p>
  
  <ul>
  <li>I click on an Image (Touchable-Opacity set the state modalShow
  The Landscape-Mode will be switched to Portrait-Mode, after that the Modal appears</li>
  <li>If I close the Modal, the App switch back to Landscape-Mode.</li>
  </ul>
  
  <p>Any Idea, why this only happend on Iphone, but working well on Android?</p>
