  注意 - 我没有xamarin经验，但我知道“window.open（）”js如何在WKWebView中使用本机代码，所以我希望这个答案可以帮助你连接丢失的点 .

  首先，在您配置Web视图的位置设置UIDelegate ..（在您的案例中为viewDidLoad）

  webView.uiDelegate = self
  

  其次，实现UIDelegate的这种协议方法 . 我们的想法是即时创建一个Web视图和一个视图控制器，然后呈现/推送它并将此Web视图实例返回给WebKit，以便它可以与父Web视图 Build 链接并加载url（窗口的第一个参数） . 公开电话） .

  func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
          let childWebView = WKWebView(frame: .zero, configuration: configuration)   // Must use the configuration provided by this method
          let webViewController = ViewController() // create an instance of a new view controller that you want to push or present with a web view
          webViewController.webView = childWebView // provide this new child web view to view controller for layout purpose 
          navigationController?.pushViewController(webViewController, animated: true)
          return childWebView
  }

  • 由于方法 DecidePolicy 包含在 IWKNavigationDelegate 中，因此您应该实现它 WKUIDelegate .

  • Export 内的方法字符串不完整，应为 [Export("webView:decidePolicyForNavigationAction:decisionHandler:")]

  有两种方法可以实现委托 .

  Strong Delegate:

  public override void ViewDidLoad()
  {
      base.ViewDidLoad();
      WKWebView webview = new WKWebView(this.View.Bounds,null);
      webview.NavigationDelegate = new MyWKNavigationDelegate();
  }
  
  class MyWKNavigationDelegate : WKNavigationDelegate
  {
      public override void DecidePolicy(WKWebView webView, WKNavigationAction navigationAction, Action<WKNavigationActionPolicy> decisionHandler)
      {           
      }
  }
  

  Weak Delegate:

  public override void ViewDidLoad()
  {
      base.ViewDidLoad();
      WKWebView webview = new WKWebView(this.View.Bounds,null);
      webview.WeakNavigationDelegate = this;
  }
  
  [Export("webView:decidePolicyForNavigationAction:decisionHandler:")]
  public  void DecidePolicy(WKWebView webView, WKNavigationAction navigationAction,  Action<WKNavigationActionPolicy> decisionHandler)
  {
  }
