我想为iPhone上的“添加主屏幕”图标和“添加书签/收藏夹”图标添加不同的图标。 我已经阅读了很多有关此问题的文档，但找不到如何实现此目的。
我从Apple开发人员网站上找到了一些链接，但是它没有告诉我问题
为此， 我需要在head标签中配置apple-touch-icon链接吗？

<link rel="apple-touch-icon" sizes="57x57" href="/apple-touch-icon-57x57.png">
<link rel="apple-touch-icon" sizes="57x57" href="/apple-touch-icon-57x57-precomposed.png">

</head>
尽管我是这样配置的，但如果根文件夹上有一个名为apple-touch-icon-120x120.png的文件，则会从ROOT文件夹中获取“收藏夹”图标。这是我的问题的其他问题。我的主要问题是如何通过代码区分主屏幕图标和书签/收藏夹？
