title: Invoke method in objective c code from HTML code using UIWebView
body: <p>I have .html file in my iOS app. HTML file has few div blocks with onClick methods.
  When I tap on these blocks I invoke some javascript code in web view, but I need also know about these events in my source code.</p>
  
  <p>For example when I tap on web element and onClick is called I need to invoke some method in the code e.g. <code>- (void)didTouchedWebElementWithId</code></p>
  
  <p>Can I do this stuff. Thanks.</p>
