ios - 内容更改时 WKWebView 不调整大小

Question

当内容更改时，WKWebView 不会调整大小。

这是一个代码片段:

@IBOutlet weak var containingView: UIView!
var webView: WKWebView! 

override func viewDidLoad()
{
    super.viewDidLoad()

    let contentController = WKUserContentController();
    self.webView = WKWebView(frame: CGRectMake(0, 0, self.view.frame.width, self.view.frame.height), configuration: WKWebViewConfiguration())
    self.webView.autoresizingMask = [.FlexibleHeight]
    self.webView.loadHTMLString(__, baseURL: __))
    self.webView.scrollView.bounces = false
    self.webView.scrollView.scrollEnabled = false

    self.containingView.addSubview(self.webView)
}

应该添加什么功能以便我可以拦截正在更改的内容大小并相应地更改 containingView 大小？

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    print("webview did enter did finish navigation")
    webView.evaluateJavaScript("document.readyState", completionHandler: { (complete, error) in
        if complete != nil {
            webView.evaluateJavaScript("document.body.scrollHeight", completionHandler: { (result, error) in
                if let heightOfContent = result as? CGFloat {

                }
            })
        }
    })
}
