是否将.html从iOS应用程序资源加载到WebView？

// 创建UIWebView实例
let webView = UIWebView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))

// 获取.html文件的URL
guard let htmlFile = Bundle.main.path(forResource: "index", ofType: "html") else {
    return
}

let htmlURL = URL(fileURLWithPath: htmlFile)

// 加载.html文件
let request = URLRequest(url: htmlURL)
webView.loadRequest(request)

// 将webView添加到视图层次结构中
view.addSubview(webView)

// 创建WKWebView实例
let webView = WKWebView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))

// 获取.html文件的URL
guard let htmlFile = Bundle.main.path(forResource: "index", ofType: "html") else {
    return
}

let htmlURL = URL(fileURLWithPath: htmlFile)

// 加载.html文件
let request = URLRequest(url: htmlURL)
webView.load(request)

// 将webView添加到视图层次结构中
view.addSubview(webView)
