title: Rendering PDF in UIWebView iOS 8, causes a black border around PDF
body: <p>In iOS 8, when rendering a .PDF into a <code>UIWebview</code> there is a black border and background around the PDF displayed (not the whole background view).  Note this is not the UIWebview background which is set to:</p>
  
  <pre><code>myWebView.opaque = NO;
  myWebView.backgroundColor = [UIColor clearColor];
  </code></pre>
  
  <p>This is not present in &lt; iOS8,  (no black bordering coloured background around the .PDF)</p>
  
  <p>Anyone else experienced this who could shed some light on this?</p>
  
  <p>Im loading my PDF into the Web view like so..</p>
  
  <pre><code>- (void)viewWillAppear:(BOOL)animated
  {
  
      [super viewWillAppear:animated];
      if (self.pdfData != nil &amp;&amp; self.viewHasUnloaded == YES) {
          self.viewHasUnloaded = NO;
          [self.webView loadData:self.pdfData MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil];
      }
  }
  </code></pre>
