title: Get notified about a page change in UIWebView
body: <p>I'm curious if there's a way to detect a change of the displayed website inside a <code>UIWebView</code>. In an app I'm working on we're using a <code>UIWebView</code> to present a part of the functionality which are basically a few steps the user needs to follow. However, the will be a specific page at the end of these steps that I need to identify and after which the app needs to display a different view.</p>
  
  <p>Unfortunately the <code>UIWebViewDelegate</code> doesn't seem to do the trick.</p>
