title: Get a parameter from NSURL
body: <p><br />
  In my application I need to get parameters "access_token" and "user_id" from this url :<br /> <a href="https://oauth.vk.com/blank.html#access_token=b1b33dfaa3&amp;expires_in=86400&amp;user_id=311515" rel="nofollow">https://oauth.vk.com/blank.html#access_token=b1b33dfaa3&amp;expires_in=86400&amp;user_id=311515</a>
  <br /><br />
  Here is My code for accessing the "user_id" parameter in webViewDidFinishLoad: </p>
  
  <pre><code>NSArray *userAr = [[[[webView request] URL] absoluteString] componentsSeparatedByString:@"&amp;user_id="];
  
  NSString *user_id = [userAr lastObject];
  </code></pre>
  
  <p><br /></p>
  
  <p>How do I get the "access_token"? If I use the same method it doesn't work...</p>
