Swift

/ 方法一 加载路径 这种方法加载不了html的图片
        let htmlPath = Bundle.main.path(forResource: "index", ofType: "html")
        if let htmlPath =  htmlPath {
            let url = URL.init(fileURLWithPath: htmlPath) // 把字符串 转成 URL 类型
            let request = URLRequest(url: url)
            self.webView.load(request)
            self.webView.navigationDelegate = self
        }

加载本地html，并且加载图片

let bundlePath = Bundle.main.bundlePath
let path = "file://\(bundlePath)/assets/index.html"
let url = URL(string: path);
let request = URLRequest(url: url!)
self.webView.load(request)
