Ios WKWebview未加载本地HTML/CSS文件

我正在使用WKWebview加载本地html文件。该文件夹位于tmp目录中。js和css的相对路径位于嵌套文件夹中。（../css/font.css，../js/player.js），其中作为父文件夹中的html。未在wkwebview中加载Url

Root folder name - HTMLFiles
Root HTML Path -  HTMLFiles/HTML/index.html
CSS path - HTMLFiles/design/CSS/font.css
JS path - HTMLFiles/JSPath/JS/player.js

---

WKWebView仅从本地存储加载html。您可以用于加载文件。

如果在打印urlToLoad字符串时，您可以通过编辑问题正文来澄清您的问题吗？
