将信用卡添加到钱包Apple Pay中

Question

我正在尝试在我的iOS Xamarin应用程序上实现设置Apple Pay按钮。我已经为它添加了按钮和单击处理程序。然后使用PKPassLibrary.OpenPaymentSetup（）打开Wallet。然后，如果用户成功地将卡添加到钱包中，我需要通过更改“设置ApplePay按钮”为“用Apple Pay支付”来处理此事件。但我找不到工作的任何事件处理程序或类似的东西。

我试过的：

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。

附注：我想我可能观察到了不正确的事件。

请尝试使用以下代码：

     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
         }

还有一些其他的付款方式，你可以把它们签入
