title: UIWebView: when did a page really finish loading?
body: <p>I need to know, when a web page has completely been loaded by UIWebView. I mean, really completely, when all redirects are done and dynamically loaded content is ready.
  I tried injecting javascript (querying for <code>document.readyState == 'complete'</code>), but that does not seem to be very reliable.</p>
  
  <p>Is there, maybe, an event from the private api that will bring me the result?</p>
