Answer 1

如果您设置了PKPaymentAuthorizationViewControllerDelegate方法,则可以在此方法中捕获取消:

    - (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller

在我调用Apple Pay之前,我将布尔值(applePaymentDidSucceed)设置为FALSE,如果此方法中的"PKPaymentAuthorizationStatus"为真,则将其设置为true:

    - (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
                   didAuthorizePayment...

如果(!applePaymentDidSucceed),用户取消了.
