title: get current Domain of UIWebview
body: <p>I want to get the current domain of UIWebView</p>
  
  <p>For example:</p>
  
  <p><a href="http://a.m.tmall.com/i15104234454.htm?sid=a0c935526ab19ee7051225579c90cf96&amp;spm=875.124399.275145.1" rel="nofollow">http://a.m.tmall.com/i15104234454.htm?sid=a0c935526ab19ee7051225579c90cf96&amp;spm=875.124399.275145.1</a> -> tmall.com</p>
  
  <p>Is there any reliable way to do this?</p>
  
  <p>I saw someone suggest this:</p>
  
  <pre><code> NSString *currentURL = myWebView.request.URL.absoluteString;
  </code></pre>
  
  <p>I know regex could do it. Any other way?</p>
