swift WKWebView 原生和h5交互

WKWebView 初始化设置

let Configuration = WKWebViewConfiguration()

        let controller = WKUserContentController()

        let Preferences = WKPreferences()

        Configuration.preferences = Preferences

        controller.add(self, name: "doActionMsg")  //  注入js方法

        Configuration.preferences.javaScriptEnabled = true

        Configuration.preferences.javaScriptCanOpenWindowsAutomatically = true

        Configuration.allowsInlineMediaPlayback = true

        if #available(iOS 9.0, *) {

            Configuration.requiresUserActionForMediaPlayback = false

        } else {

            // Fallback on earlier versions

        }

        Configuration.userContentController = controller

        let processPool = WKProcessPool()

        Configuration.processPool = processPool

        webView = WKWebView(frame: CGRect(x: 0, y: 0, width: Wi, height: Hi-navigationTopHeight), configuration: Configuration)

        webView.backgroundColor = UIColor.white

        let request = URLRequest(url: URL(string: self.urlString)!)

//        webView.navigationDelegate = self

//        webView.uiDelegate = self

        webView.load(request as URLRequest)

        webView.scrollView.showsVerticalScrollIndicator = true

        webView.scrollView.delegate = self

        self.view.addSubview(webView)

WKWebView代理方法

func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {

        if message.name == "doActionMsg" {  // 约定好的方法

if let bodyStr:String = message.body as? String { //  返回参数

                let dict:Dictionary = getDictionaryFromJSONString(jsonString: bodyStr)

                print("dict____",dict)

}

}
