title: iOS 7 UIWebView not rendering
body: <p>I'm porting my app to iOS 7 and I have a problem with UIWebView in iOS 7.
  I load local html string in it with this code:</p>
  
  <pre><code>NSURL *baseURL = [NSURL fileURLWithPath: DOCUMENTS_DIRECTORY];
  [self.descWebView loadHTMLString:html baseURL:baseURL];
  </code></pre>
  
  <p>It works perfectly on iOS 6 and prior but on iOS 7 it doesn't rendering and the UIWebView is still white. And this message appears in console:</p>
  
  <pre><code>void SendDelegateMessage(NSInvocation *): delegate
  (webView:decidePolicyForNavigationAction:request:frame:decisionListener:)
  failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode
  </code></pre>
  
  <p>Thanks for your replies.</p>
