Xamarin.Forms ios WebViewRenderer共享Cookies

Question

我正在使用WebViewRenderer设置cookie策略，并使用来自HTTPClient的登录请求共享cookie。事实证明，就像我给出的那样： var cookieJar = NSHttpCookieStorage.SharedStorage; cookieJar.AcceptPolicy = NSHttpCookieAcceptPolicy.Always;

在iphone模拟器中调试并运行webview时，浏览器会指示未启用Cookie策略，因此用户无法登录，因为webview从安全环境运行iframe。以下是代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Foundation;
using UIKit;
using Xamarin.Forms;
using Projeto.Custom;
using Projeto.iOS.Renderers;
using Xamarin.Forms.Platform.iOS;
using WebKit;
using System.IO;
using System.Net;

[assembly: ExportRenderer(typeof(CustomWebView), typeof(CustomWebViewRenderer))]
namespace Mynamespace.iOS.Renderers
{
    public class CustomWebViewRenderer : ViewRenderer<CustomWebView, WKWebView>
    {

        protected override void OnElementChanged(ElementChangedEventArgs<CustomWebView> e)
        {
            base.OnElementChanged(e);

            if(Control == null)
            {
                var userController = new WKUserContentController();
                var config = new WKWebViewConfiguration { 
                UserContentController = userController };
                var webView = new WKWebView(Frame, config);
                SetNativeControl(webView);
            }

            if(e.OldElement != null)
            {
                var hybrid = e.OldElement as CustomWebView;
                hybrid.Cleanup();
            }

            if(e.NewElement != null)
            {
                var baseUrl = new NSUrl(NSBundle.MainBundle.BundlePath, 
                true);
                string content = Element.Uri;
                Control.LoadHtmlString(content, baseUrl);              

                var cookieUrl = new 
                Uri("https://secure.gooddata.com/gdc/account/login");
                var cookieJar = NSHttpCookieStorage.SharedStorage;
                cookieJar.AcceptPolicy = NSHttpCookieAcceptPolicy.Always;
                foreach (var aCookie in cookieJar.Cookies)
                {
                    cookieJar.DeleteCookie(aCookie);
                }

                var jCookies = 
                CustomCookie.CookieContainer.GetCookies(cookieUrl);
                IList<NSHttpCookie> eCookies =
                    (from object jCookie in jCookies
                     where jCookie != null
                     select (Cookie)jCookie
                     into netCookie
                     select new NSHttpCookie(netCookie)).ToList();
                cookieJar.SetCookies(eCookies.ToArray(), cookieUrl, cookieUrl);

            }
        }
    }
}

如果有人能告诉我在ios原生WebView中启用cookie策略的最佳方法，我将不胜感激。
