Zend Framework Controller File (Apple Icons)
===

Question about including some header information in controller file in zend framework.  I am wanting to include the apple icons.  Going off of this here: http://gigaom.com/apple/how-to-create-ios-device-home-screen-icons-for-web-sites/

However the 'sizes' block is not showing up when I look at the actual source of page that this is on.  I'm assuming rel and href are native to zend framework already.  How do I get the 'sizes' to show up?  

    $this->view->headLink(array('rel' => 'apple-touch-icon', 'href' => '/images/icons/apple-touch-icon.png'));
		$this->view->headLink(array('rel' => 'apple-touch-icon', 'sizes' => '72x72', 'href' => '/images/icons/apple-touch-icon-72x72.png'));
	    $this->view->headLink(array('rel' => 'apple-touch-icon', 'sizes' => '114x114', 'href' => '/images/icons/apple-touch-icon-114x114.png'));


This is what is actually showed upon viewing source of page in header.

    <link href="/images/icons/apple-touch-icon.png" rel="apple-touch-icon" />
    <link href="/images/icons/apple-touch-icon-72x72.png" rel="apple-touch-icon" />
    <link href="/images/icons/apple-touch-icon-114x114.png" rel="apple-touch-icon" />

    

Thanks
