title: iPhone - UIWebview - Get the URL of the link clicked
body: <p>I'm creating an app which has a text field &amp; go button on top and web view below them.
  When user enters URL in text field and clicks "Go" button, it will start loading the page in webview.
  When user clicks on some link, i want to show the URL of the page (being loaded) in the text field.
  How can I get that URL of the link clicked.</p>
  
  <p>Also some websites are there which will redirect to some other site. So my question is how to show the URL of the page being loaded in the text field?</p>
