Wordpress导航菜单图像没有显示在移动Safari中

Question

我有一个有趣的问题，我一直在试图解决过去几天。我创建了一个第二导航菜单，并通过将此代码添加到我的custom_functions.php它添加到论文1.8.5边栏：

/* Add second menu to sidebar 1*/ 
register_nav_menu('secondary', 'Secondary Menu'); 
function secondary_menu() { 
wp_nav_menu(array('container_class' => 'secondary_menu', 'theme_location' => 'secondary'  )); 
} 
add_action('thesis_hook_before_sidebar_1','secondary_menu'); 

然后我加入这个CSS来custom.css创建菜单项的图标：

/* Menu Container */ 
.custom .sidebar .menu { 
    list-style: none; 
    padding: 0; 
    margin: 0 0 0 10px; 
    width: 190px; 
    height: 190px; 
    position: relative; 
} 

/* Submenu Container */ 
.custom .sidebar .sub-menu { 
    list-style: none; 
    padding: 0; 
    margin: 0; 
    width: 190px; 
    height: 45px; 
    position: relative; 
} 
/* Facebook */ 
.custom #menu-item-15470 a { 
    display:block; 
    height:81px; 
    width:80px; 
    padding:0px; 
    margin-left:0px; 
    position: relative; 
    left: 0px; 
    top: 0px; 
    outline:none; 
    text-indent:-9999px; 
    background-image:url("http://www.hungryrunnergirl.com/wp-content/uploads/2013/01/Social_Sprite.png"); background-position:0 0px;

.custom #menu-item-15470 a:hover {

菜单图标在所有浏览器（包括手机浏览器）上都正确显示，但不在移动Safari（仅显示链接）中显示。

它应该如何看：

它似乎工作正常。我正在使用iOS模拟器（官方Apple工具）。我尝试了iPhone和iPad。您遇到缓存问题吗？
