Shortcut icon to IOS devices

I tried adding all the apple icons to the root directory as well as the favicon to the themes directory. And redployed tomcat but I cannot see shortcut icon of my web page on IOS devices as a webclip.

I followed Specifying a Webpage Icon for Web Clip from the below

Also I added the following lines to my code.

    TouchKitSettings s = getTouchKitSettings();
    String contextPath = getServletConfig().getServletContext().getContextPath();
    s.getApplicationIcons().addApplicationIcon(contextPath + "/VAADIN/themes/mytheme/apple-icon.png");

Am I missing something?
