无法连接到iTunes存储Xamarin形式

Question

[enter image description here Hi，您好，谢谢。我在我的Xamarin表格ios中遇到问题。问题是，当我要购买产品时，抛出了一个异常，无法连接到iTunes，将我的相同代码存储在xamarin表单android上可以正常工作。我的恢复购买代码可以正常工作。

这是我的购买代码

private async Task<bool> MakePurchase(string ProductId, string Payload)
    {
        if (!CrossInAppBilling.IsSupported)
        {
            return false;
        }

        var billing = CrossInAppBilling.Current;
        try
        {
            var connected = await billing.ConnectAsync();

      if (!connected)//Couldn't connect to billing, could be offline, 
   alert user
            {
                DependencyService.Get<IToast>().Show("Something went 
                wrong or you may not connected with the internet!");
                return false;
            }

            //try to purchase item
            var purchase = await billing.PurchaseAsync(ProductId, 
            ItemType.InAppPurchase, Payload);

            if (purchase == null)
            {
                return false;
            }
            else
            {
                //Purchased, save this information
                var responseId = purchase.Id;
                var responseToken = purchase.PurchaseToken;
                var state = purchase.State;
                return true;


            }
        }
        catch (InAppBillingPurchaseException ex)
        {
            if (ex.PurchaseError == PurchaseError.DeveloperError)
            {
                DependencyService.Get<IToast>().Show("DeveloperError");
                ex.Message.ToString();
            }

            else if (ex.PurchaseError == PurchaseError.AlreadyOwned)
            {
                DependencyService.Get<IToast>().Show("AlreadyOwned");
                return true;
            }
            else if(ex.PurchaseError == PurchaseError.BillingUnavailable)
            {
                DependencyService.Get<IToast> 
           ().Show("BillingUnavailable");
                return false;
            }
             else if(ex.PurchaseError == PurchaseError.InvalidProduct)
            {
                DependencyService.Get<IToast>().Show("InvalidProduct");
                return false;
            }

             else if(ex.PurchaseError == PurchaseError.ItemUnavailable)
            {
                DependencyService.Get<IToast>().Show("ItemUnavailable");
                return false;
            }
            else if(ex.PurchaseError == PurchaseError.GeneralError)
            {
                DependencyService.Get<IToast>().Show("General Error");
                return false;
            }

            //Something bad has occurred, alert user
        }
        finally
        {
            //Disconnect, it is okay if we never connected
            await billing.DisconnectAsync();
        }

        return false;
    }

您有没有做过这项工作？我现在正在PCL / FORMS应用程序上测试InAppBilling，并且遇到相同类型的问题。我正在使用James代码的3.0.0 beta版。
