最后，解决了上面的问题。我收到错误

Finally, solved the problem above. I was receiving errors

• 无法发出服务信号com.apple.WebKit.WebContent：113：找不到指定的服务

• Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service

因为我没有在视图上添加 WKWebView 对象作为子视图并尝试在其顶部调用 -loadHTMLString：baseURL：。只有在成功加载后，我才将其添加到视图的子视图中 - 这是完全错误的。我的问题的正确解决方案是：

Since I have not added WKWebView object on the view as a subview and tried to call -loadHTMLString:baseURL: on the top of it. And only after it was successfully loaded I was adding it to view's subviews - which was totally wrong. The correct solution for my problem is:

1。添加 WKWebView 对象以查看子视图数组

2. 调用 -loadHTMLString：baseURL：最近添加了 WKWebView
