Swift3 不同视图控制器中的Swift 3 WKWebView打开链接（url）'；WKS网络视图,swift3,wkwebview,Swift3,Wkwebview,我尝试了下面的代码，但不确定如何将request.url传递给第二个ViewController的WKWebView func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool { switch navigationType{ case .linkClicked

我尝试了下面的代码，但不确定如何将request.url传递给第二个ViewController的WKWebView

 func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    switch navigationType{
                case .linkClicked:
   self.performSegue(withIdentifier: "mySeque", sender:self)


                return false


            default:
                return true

            }
}

您需要将URLRequest和WKWebViewConfiguration从第一个WKWebViewController传递到第二个WKWebViewController

guard let secondURLRequest = secondURLRequest else 
{ fatalError("No secondURLRequest") }

guard let secondWebConfiguration = secondWebConfiguration else 
{ fatalError("No webConfiguration") }

//WKWebView
seconWKWebView = WKWebView(frame: <yourValue>, configuration: secondWebConfiguration)

请参阅下面的实施

在FirstWKWebViewController中，将全局变量保持为

var firstURLRequest: URLRequest?

假设您的WKWebView是

firstWebView

将代码修改为

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

switch navigationType{

            case .linkClicked:

                 firstURLRequest = request //<---code add
                 self.performSegue(withIdentifier: "mySeque", sender:self)
                 return false

            default:
                return true
        }

然后在FirstWKWebViewController中，在segue调用之前通过WebConfiguration和URLReqest

func prepare(for segue: UIStoryboardSegue, sender: Any?) {

    if let segueIdentifier = segue.identifier {

        switch segueIdentifier { 
        case "mySeque":

            if let secondWKWebVC = segue.destination as? SecondWKWebViewController {
                if nsurlreq != nil { secondWKWebVC.secondURLRequest = nsurlreq! as URLRequest }
                secondWKWebVC.secondWebConfiguration = firstWebView.configuration     
            } 
        default:
            return
        }
    }

}

然后在第二个WebViewController中

guard let secondURLRequest = secondURLRequest else 
{ fatalError("No secondURLRequest") }

guard let secondWebConfiguration = secondWebConfiguration else 
{ fatalError("No webConfiguration") }

//WKWebView
seconWKWebView = WKWebView(frame: <yourValue>, configuration: secondWebConfiguration)

guard let secondURLRequest=secondURLRequest else
{fatalError（“无第二个URL请求”）}
guard let secondWebConfiguration=secondWebConfiguration else
{fatalError（“无网络配置”）}
//WKWebView
seconWKWebView=WKWebView（帧：，配置：secondWebConfiguration）
