title: Generating apple-touch-icon using Rails
body: <p>I am trying to add the apple-touch-icon link to my application head so that it will be displayed on homescreen bookmarks.  The Rails guides state the following: </p>
  
  <blockquote>
    <p>Mobile Safari looks for a different link tag, pointing to an image that will be used if you add the page to the home screen of an iOS device. The following call would generate such a tag:</p>
  </blockquote>
  
  <pre><code>favicon_link_tag 'mb-icon.png', rel: 'apple-touch-icon', type: 'image/png'
  &lt;link href="/assets/mb-icon.png" rel="apple-touch-icon" type="image/png" /&gt;
  </code></pre>
  
  <p>However when I use the following (timestamps removed):</p>
  
  <pre><code>&lt;%= favicon_link_tag 'favicon.ico' %&gt;
  &lt;%= favicon_link_tag 'apple-icon.jpeg', rel: 'apple-touch-icon', type:'image/jpeg' %&gt;
  </code></pre>
  
  <p>it does not correctly generate the apple-touch-icon (favicon works as expected).  It inserts "images" and not "assets" into the href. The code generated is:</p>
  
  <pre><code>&lt;link href="/assets/favicon.ico" rel="shortcut icon" type="image/vnd.microsoft.icon"&gt;
  &lt;link href="/images/apple-icon.jpeg" rel="apple-touch-icon" type="image/jpeg"&gt;
  </code></pre>
  
  <p>I have also tried just putting the link right into the application file without using the TagHelper, but it doesn't append the timestamp to the file, so the file isn't correct.</p>
