ios - 在打开/加载之前加载/刷新 WKWebView

Question

如何在网页 View 打开/显示之前刷新/加载 .html 页面的所有内容？

这是我的代码:

    class ContactViewController: UIViewController {


    @IBOutlet weak var AboutWebView: WKWebView!

    let url = URLAddress()


    override func viewDidLoad() {

        super.viewDidLoad()


        let url = URL(string: "https://www.myfakeurl.com/about.html")
        let request = URLRequest(url: url!)

        AboutWebView.load(request)


    }



    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }




}

如何用我的代码调整它？

只需隐藏 Web View ，直到其完全加载并在 webView(_:didFinish:) 中显示它即可。

请注意，您应该使 View Controller 符合 WKNavigationDelegate。

class ContactViewController: UIViewController, WKNavigationDelegate {
    override func viewDidLoad() {
        [...]
        aboutWebView.navigationDelegate = self
        aboutWebView.isHidden = true
    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        webView.isHidden = false
    }
}
