title: iOS Transparent background for WKWebView
body: <p>I'm in the process of migrating some code over from UIWebView to a WKWebView on a iOS project.
  I'm currently trying to make a wkwebview transparent but the functionality doesn't seem work.
  I could do this on a UIWebView by doing this</p>
  
  <pre><code>self.opaque = NO;  
  self.backgroundColor = [UIColor clearColor];  
  </code></pre>
  
  <p>and setting the html page to be transparent via styling would allow me to see the view content underneath.</p>
  
  <p>If I try the same code on a WKWebView the background of the html page isn't becoming transparent.
  I've had search on google and there seems to be work around for MacOS X but I can't see to find a solution for iOS.</p>
  
  <p>This is how it's done on a UIWebView (<a href="https://stackoverflow.com/questions/3646930/how-to-make-a-transparent-uiwebview">How to make a transparent UIWebView</a>)
  Has anyone any ideas if this is possible?</p>
  
  <p>Thank you.</p>
