将 Xcode 更新到 10.4 版后 Apple Pay 无法正常工作答案

【问题标题】：Apple Pay not working after update Xcode to version 10.4将 Xcode 更新到 10.4 版后 Apple Pay 无法正常工作

【问题描述】：

Apple Pay 在模拟器中运行良好，但将 Xcode 升级到 10.4 后停止运行。

Apple Pay 弹出窗口出现。
点击密码支付后，不验证支付就隐藏了。
方法- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didAuthorizePayment:(PKPayment *)payment completion:(void (^)(PKPaymentAuthorizationStatus))completion {}没有被调用。

代码：

NSString *merchantIdentifier = [STPPaymentConfiguration sharedConfiguration].appleMerchantIdentifier;
PKPaymentRequest *paymentRequest = [Stripe paymentRequestWithMerchantIdentifier:merchantIdentifier country:@"US" currency:currencyCode];
paymentRequest.paymentSummaryItems = @[
   [PKPaymentSummaryItem summaryItemWithLabel:@"Fancy Hat" amount:[NSDecimalNumber decimalNumberWithString:amount]],
   // The final line should represent your company;
   // it'll be prepended with the word "Pay" (i.e. "Pay iHats, Inc $50")
   [PKPaymentSummaryItem summaryItemWithLabel:@"iHats, Inc" amount:[NSDecimalNumber decimalNumberWithString:amount]],
];

if ([Stripe canSubmitPaymentRequest:paymentRequest]) {
    // Setup payment authorization view controller
    PKPaymentAuthorizationViewController *paymentAuthorizationViewController = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:paymentRequest];
    paymentAuthorizationViewController.delegate = self;

    // Present payment authorization view controller
    FlutterViewController* controller = (FlutterViewController* )[[UIApplication sharedApplication].keyWindow rootViewController];
    [controller presentViewController:paymentAuthorizationViewController animated:YES completion:nil];
}

【问题讨论】：

更新到 Xcode 10.3 后出现完全相同的问题。注意到didAuthorizePayment 方法的签名已更改为func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void)，并标记为iOS11+。但是更改为新签名对我没有帮助。

【解决方案1】：

他们确实更改了签名，因此有一个新方法可以调用 iOS11+，而 iOS9 和 iOS10 仍然需要旧方法：

 /// for iOS 9 and iOS 10
 func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController,
                          didAuthorizePayment payment: PKPayment,
                                           completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {
    ...
 }

 @available(iOS 11.0, *)
 func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController,
                          didAuthorizePayment payment: PKPayment,
                                              handler: @escaping (PKPaymentAuthorizationResult) -> Void) {
    ...
 }

它似乎在 12.4 模拟器中不起作用。您需要在真实设备上进行测试。具有以前 iOS 的模拟器似乎可以正常工作（iOS10 适合我）。这个问题讨论了模拟器问题：ApplePay `paymentAuthorizationViewController:didAuthorizePayment:handler:` not called in Xcode Simulator 10.3
