title: Local content URL from UIWebView
body: <p>I'm writing an ios app that uses a <code>UIWebView</code> to display local html content as a help subsystem. The user can follow links to other local html content and I want to be able to tell what page the <code>UIWebView</code> is currently displaying.</p>
  
  <p>I have tried <code>webView.request.URL.absoluteString</code> and similar variants but it gives me the app bundle and not the local html file within. How can I get the name of the local file being accessed?</p>
