title: iOS7 UIWebView wont load page, but it loads on iOS6
body: <p>I have an app with multiple webViews, on iOS6 it loads perfectly (sometimes I have to manually refresh the webviews content, and it works fine), but on iOS7 (the same code, the same sdk-ios7sdk) the webViews loads the first time, then if i hit refresh i get -999 error code, if i navigate to a page, then refresh the webviews data, then go back to view the webview, it works...</p>
  
  <p>Here's the error message:</p>
  
  <pre><code>Error Domain=NSURLErrorDomain Code=-999 "The operation couldn’t be completed.
  (NSURLErrorDomain error -999.)" UserInfo=0x9ba3220 
  {NSErrorFailingURLKey=file:///Users/jakaba/Library/Application%20Support/

  NSErrorFailingURLStringKey=file:///Users/jakaba/Library/Application%20Support/
  iPhone%20Simulator/7.0/Applications/.../myapp.app/page.html}
  </code></pre>
  
  <p>Any idea?
  Thank you in advance!</p>
