title: Calling a method when UIWebView scrolls
body: <p>I have a UIWebView that contains a lot of text content. I need to be able to get the location of the UIWebView every time it moves. I am using this code to get the point:</p>
  
  <pre><code>pageYOffset = [[webView stringByEvaluatingJavaScriptFromString:@"window.pageYOffset"] intValue];
  </code></pre>
  
  <p>now I just need to make it so that this variables value is updated everytime the UIWebView position moves, or there is any scrolling. Is it possible to call a method whenever the UIWebView scrolls?</p>
