title: Dynamic height of UIWebView
body: <p>I have a problem with setting the height of an <code>UIWebView</code> dynamically. The webview loads a product description which contains html. I want the <code>UIWebView</code> to change its height based on the contents of the description.
  I need to do it with <code>webViewDidFinishLoad</code> function. But I can not write function content.</p>
