WKWebView委托方法更改

Question

我正在努力将UIWebView迁移到WKWebView。我已经更改了所有Delegate方法。我需要WKWebView委托方法等于下面的UIWebView委托方法。

我在UIWebView中写了下面的方法。帮我将下面的代码更改为WKWebView

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {

    guard let url = request.url else {
       return true
    }

    guard !url.absoluteString.contains("data:application/pdf") else {
        navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.action,
                                                            target: self,
                                                            action: #selector(share(sender:)))
        return true
    }

    guard url.pathExtension != "pdf" else {
        let safariVC = SFSafariViewController(url: url)
        safariVC.modalPresentationStyle = .popover
        present(safariVC, animated: true, completion: nil)
        return false
    }

    guard url.isLogin() == false else {
        AppDelegate.navigationController.signOut(.sessionOnly)
        return false
    }

    guard let mobileSite = url.asMobileSite() else {
        return true
    }

    let mobileRedirect = URLRequest(url: mobileSite)
    webView.loadRequest(mobileRedirect)
    return false

}
