H5 应用封装成 ios app（PWA ），无需开发者账号。

ios提供了PWA支持，通过manifest.json来配置具体属性，包含应用名称，应用图标等。具体示例如下：

1. 在h5 首页中加入 manifest

2. 首页同级目录中添加 site.webmanifest文件，文件内容如下：

{
  "background_color": "#ffffff",
  "description": "ddd.",
  "display": "standalone",
  "icons": [
    {
        "src": "icon/icon192.png",
        "sizes": "192x192",
        "type": "image/png",
        "purpose": "any"
    },
    {
        "src": "icon/icon196.png",
        "sizes": "196x196",
        "type": "image/png",
        "purpose": "maskable"
    },
    {
        "src": "icon/icon256.png",
        "sizes": "256x256",
        "type": "image/png",
        "purpose": "any"
    },
    {
        "src": "icon/icon512.png",
        "sizes": "512x512",
        "type": "image/png",
        "purpose": "any"
    }
],
  "name": "ddd",
  "prefer_related_applications": false,
  "scope": "/",
  "short_name": "name",
  "start_url": "/?source=pwa",
  "theme_color": "#ffffff"
}
