我被卡住了，函数“userContentController”从未调用过。

用户内容控制器功能

func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
        print("Function Called")
        let showData = message.body as? String
        print(showData ?? "No Value received")
    }

viewDidLoad

        super.viewDidLoad()

        let configuration = WKWebViewConfiguration()
        configuration.userContentController.add(self, name: "send")
        let rect = CGRect(x: 0, y: 0, width: 100, height: 100)
        let wweb = WKWebView(frame: rect, configuration: configuration)


        if let filePath = Bundle.main.url(forResource: "Script", withExtension: "html") {
            let request = NSURLRequest(url: filePath)
            wweb.load(request as URLRequest)
        }
    }

剧本


window.webkit.messageHandlers.send.postMessage（“来自JavaScript的地狱”）；

尝试在脚本中传递字典而不是字符串

例如：

Swift中的window.webkit.messageHandlers.send.postMessage（{“body”：“Hell from JavaScript”}）

？国家统计局字典；让str=dict？[“body”]as？一串

<html>
    <script>
        window.webkit.messageHandlers.send.postMessage("Hell from JavaScript");
    </script>
