ios - 处理添加到钱包 Apple Pay 的信用卡

Question

我正在尝试在我的 iOS Xamarin 应用程序上实现 SetUp Apple Pay 按钮。我已经为它添加了按钮和点击处理程序。然后我使用 PKPassLibrary.OpenPaymentSetup() 打开电子钱包。然后，如果用户已成功将卡添加到钱包中，我需要通过将“设置 ApplePay 按钮”更改为“使用 Apple Pay 付款”来处理此事件。但是我找不到工作任何事件处理程序或类似的东西。

我尝试过的:

private PKPassLibrary _library;
private NSObject _walletNotificationSubscription;
private void OnSetuApplePayClicked(object button, EventArgs args)
{
   _library = new PKPassLibrary();
   _library.OpenPaymentSetup();
    _walletNotificationSubscription = PKPassLibrary.Notifications.ObserveDidChange(_library, HandleEventHandler);
}
void HandleEventHandler(object sender, NSNotificationEventArgs e)
      {
         _walletNotificationSubscription.Dispose();

         ViewModel.UpdateApplePay();
         SetButtonVisibility();
      }

但它不起作用。

P.S.:我想我可能观察到了不正确的事件。

尝试使用以下代码:

     if(PKPaymentAuthorizationViewController.CanMakePayments)
         {
            //the device supports Apple Pay

            //check whether the user can make a payment with a bank card ,such as Amex ,MasterCard,Visa,ChinaUnion and so on
            NSString[] paymentString = { PKPaymentNetwork.Amex, PKPaymentNetwork.ChinaUnionPay, PKPaymentNetwork.MasterCard, PKPaymentNetwork.Visa };

            if(PKPaymentAuthorizationViewController.CanMakePaymentsUsingNetworks(paymentString))
            {
                //user has added bank card ,do something you want
            }
            else
            {
                //user has not added bank card
            }

         }
       else
         {
            //the device doesn't support Apple Pay
         }
