用于简单 WKWebView 的 loadHTMLString 在运行时崩溃，错误 WebPageProxy::processDidTerminate: (pid 0)，原因 3

Question

我正在尝试使用带有单个按钮的简单 WKWebView，单击该按钮后应通过 JavaScript 回调到 Swift。但是，我在 Xcode 控制台中看到以下日志，并且视图加载空 WKWebView:

[pageProxyID=5, webPageID=6, PID=0] WebPageProxy::processDidTerminate: (pid 0), reason 3

[pageProxyID=5, webPageID=6, PID=0] WebPageProxy::dispatchProcessDidTerminate: reason = 3

[pageProxyID=5, webPageID=6, PID=84636] WebPageProxy::processDidTerminate: (pid 84636), reason 3

[pageProxyID=5, webPageID=6, PID=84636] WebPageProxy::dispatchProcessDidTerminate: reason = 3

[pageProxyID=5, webPageID=6, PID=84636] WebPageProxy::tryReloadAfterProcessTermination: process crashed and the client did not handle it, not reloading the page because we reached the maximum number of attempts

我初始化 WKWebView 和设置回调的代码如下所示：

   override func viewDidLoad() {
        super.viewDidLoad()
        let config = WKWebViewConfiguration()
        config.userContentController.add(self, name: "callback")
        wkWebView = WKWebView(frame: self.view.frame, configuration: config)
        wkWebView.autoresizingMask = [.height, .width]
        self.view.addSubview(wkWebView)
        
        let htmlStr = "<!DOCTYPE html><html><body><button type=\"button\" onclick=\"myFunction()\">My Button</button><script type=\"text/javascript\">function myFunction() { window.webkit.messageHandlers.callback.postMessage('clicked!'); }</script></body></html>"
        self.wkWebView.loadHTMLString(htmlStr, baseURL: Bundle.main.resourceURL)
   }

花了一段时间才明白——因为我的应用是沙盒化的——我需要在签名和功能下启用网络连接，这反过来又为启动 WKWebView 的项目添加了适当的权利，并期待已久 My Button。 我现在也能在点击这个按钮时得到回调！

希望这对遇到同样情况的人有所帮助。
