Xcode 项目结构

HTML 页面内容示例

我写了这段代码来加载 WKWebView

I wrote this code to load WKWebView

let htmlFile = Bundle.main.path(forResource: "provisiontech", ofType: "htm")
let html = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
let baseURL = Bundle.main.resourceURL!.appendingPathComponent("pvtc")
webView.loadHTMLString(html!, baseURL: baseURL)

推荐答案

webview 无法访问资源文件夹.您应该改用 loadFileURL(_:allowingReadAccessTo:).不需要预加载数据，例如:

The webview has no access to the resource folder. You should use loadFileURL(_:allowingReadAccessTo:) instead. Preloading the data is not neccessary, e.g.:

let url = Bundle.main.url(forResource: "provisiontech", ofType: "htm")

webView.loadFileURL(url, allowingReadAccessTo:
    Bundle.main.resourceURL!.appendingPathComponent("pvtc"))

如果webview仍然无法访问资源，则应考虑是否将页面和所有资源放在同一个文件夹中.

If the webview still cannot access the resources, you should consider whether putting the page and all resources into the same folder.
