PKPaymentAuthorizationViewController在iOS 8.4上意外崩溃

背景：我在iOS 8.2、8.3上使用了相同的代码，工作正常

PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];
paymentPane.delegate = self;

[self presentViewController:paymentPane animated:TRUE completion:nil];

付款请求代码：

        PKPaymentRequest *request = [[PKPaymentRequest alloc] init];


        NSString *chargeApplePay=[NSString stringWithFormat:@"%.02f",pay];

        PKPaymentSummaryItem *total = [PKPaymentSummaryItem summaryItemWithLabel:@"Grand Total"
                                                                          amount:[NSDecimalNumber decimalNumberWithString:chargeApplePay]];

        request.paymentSummaryItems = @[total];
        request.countryCode = @"US";
        request.currencyCode = @"USD";
        request.supportedNetworks = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];
        request.merchantIdentifier = @"valid.com.myIdentifier";
        request.merchantCapabilities = PKMerchantCapability3DS;

问题：现在在iOS 8.4上，当我试图显示我的paymentPane时，不知何故它的值为零

致命异常：NSInvalidArgumentException应用程序试图 在目标上显示一个无模式视图控制器

我已经通过谷歌搜索和使用stackoverflow的答案尝试过了。

• 像这样的支票

  [PKPaymentAuthorizationViewController    canMakePaymentsUsingNetworks:@[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa]] 
  

  及

  [PKPaymentAuthorizationViewController可以付款]

• 检查我的商户id是否有效

• 检查我用于请求的所有代码是否有效

在Xcode调试器中运行时，我也遇到过类似的问题。作为一种解决方法，我在Xcode中停止应用程序，然后在iPhone或iPad上手动启动应用程序

这样做的一个缺点显然是您无法调试任何问题。我不得不求助于NSLog并阅读控制台日志

检查您是否已将

信用卡

信息添加到设备

存折

中

检查您是否可以使用您的设备付款。

目标C:

Swift:

let paymentNetworks=[PKPaymentNetworkAmex，PKPaymentNetworkMasterCard，PKPaymentNetworkVisa]
如果PKPaymentAuthorizationViewController.CanMakeMPaymentSusingNetworks（paymentNetworks）{
NSLog（@“可以用您的卡付款”）；
}
否则{
NSLog（@“卡不支持”）；
}

显然，我已经完成了所有这些，并且它在iOS 8.3中工作。 if ([PKPaymentAuthorizationViewController canMakePayments]) { NSLog(@"Can Make Payments"); } else { NSLog(@"Can't Make payments"); } if PKPaymentAuthorizationViewController.canMakePayments() { NSLog(@"Can Make Payments"); } else { NSLog(@"Can't Make Payments"); } NSArray *paymentNetworks = [NSArray arrayWithObjects:PKPaymentNetworkMasterCard, PKPaymentNetworkVisa, PKPaymentNetworkAmex, nil]; if ([PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:paymentNetworks]) { NSLog(@"Can Make payment with your card"); } else { NSLog(@"Card is not supporting"); } let paymentNetworks = [PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa] if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(paymentNetworks) { NSLog(@"Can Make payment with your card"); } else { NSLog(@"Card is not supporting"); }
