title: UIActivity indicator in UIwebview
body: <p>i have seen many tutorials but none of them work:</p>
  
  <p>I have a UIwebView in my storyboard, and it loads the indicated website normally, but it takes time and I would like to use the progress indicator. I have added it to my storyboard, dragged it to the <strong>.h file</strong> (so property...) .
  In <strong>.m</strong> I added:</p>
  
  <pre><code>-(void)webViewDidStartLoad:(UIWebView *)web1{
  
  [loadingIndicator startAnimatin];
  }
  
  -(void)webViewDidFinishLoad:(UIWebView *)web1{
  
  [loadingIndicator stopAnimating];
  
  }
  </code></pre>
  
  <p>web1 is the name of my webview. 
  It does not work? Please help, thanks.</p>
