我是 PWA（渐进式 Web 应用程序）的新手，我偶然发现了以下内容：我似乎无法使用 manifest.json 文件的 display 属性。
在我的 iPhone 上将应用程序添加到我的主屏幕时，应用程序会显示在 safari 浏览器中，并显示 URL，而不是作为独立应用程序。
当（例如）我去 pokedex.org 并将其添加到我的主屏幕时，该应用程序显示为一个独立的应用程序（没有 URL 栏）。
我曾尝试使用 ngrok.io 在本地主机之外使用 https:// 托管我的应用程序，但它也无法正常工作。
我已经尝试了 safari 上的开发人员工具来重置我 iPhone 上的缓存，所以这绝对不是由缓存问题引起的。
谷歌浏览器中的应用程序选项卡说这应该是一个独立的应用程序，并且正在显示正确的徽标/网站图标。
我正在为此测试的应用程序是使用 create-react-app 构建的。

manifest.json provides metadata used when your web app is added to the
homescreen on Android. See https://developers.google.com/web/fundamentals/engage-and-retain/web-app-manifest/

Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
