title: iOS does not show/play video in UIWebView iframe
body: <p>I use UIWebView with the:</p>
  
  <pre><code>var html:String = "&lt;iframe src='http://46.101.234.111/trailers/suicide_squads_1' width='100%' height='200px' scrolling='no' frameborder='no'&gt;&lt;/iframe&gt;"
  
  cell.trailerView.loadHTMLString(html, baseURL: nil)
  </code></pre>
  
  <p>but it doesn't show/play the video on start. It just show play icon on white row and when I press on it - nothing happens. </p>
  
  <p>iframe works, I checked it. What is the problem and how can I fix it?</p>
