您可以使用WKScriptMessage和javascript对viewController进行回调并提取本机代码。

在你的viewController中：

//MARK: WKScriptMessageHandler (callback from js in HTML file)
func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage){
    if message.name == "callbackHandler" {
        print(message.body)

        //My function
        if (message.body as AnyObject).contains("myFunctionName"){
            self.playVideo()
        }
    }
}

在您的HTML文件中：

<!-- JS for Native Application Callbacks -->
<script type="text/javascript">
    function callNativeApp () {
        //iOS
        try {
            window.webkit.messageHandlers.callbackHandler.postMessage("myFunctionName");
        } catch(err) {
            console.log('The native context does not exist yet');
        }
    }
</script>
