Question

后台：我在iOS 8.2,8.3上使用了相同的代码，但它运行正常。

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

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

PaymentRequest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，当我尝试提供我的paymentPane时，其价值是以某种方式为零。

致命异常：NSInvalidArgumentException应用程序尝试过在目标上显示一个零模态视图控制器。

我已经尝试使用Google搜索并使用stackoverflow中的答案。

二手检查

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

和

[PKPaymentAuthorizationViewController canMakePayments]

检查我的商家ID是否有效。
检查我用于请求的所有代码是否有效。

Answer 1

检查您是否在设备Credit card中添加了Passbook信息。

检查您是否可以使用自己的设备付款。

目标C：

if ([PKPaymentAuthorizationViewController canMakePayments]) {
    NSLog(@"Can Make Payments");
}
else {
    NSLog(@"Can't Make payments");
}

斯威夫特：

if PKPaymentAuthorizationViewController.canMakePayments() {
    NSLog(@"Can Make Payments");
}
else {
    NSLog(@"Can't Make Payments");
}

检查您是否可以使用允许的payment networks付款。

目标C：

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");
}

斯威夫特：

let paymentNetworks = [PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa]
if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(paymentNetworks) {
    NSLog(@"Can Make payment with your card");
}
else {
    NSLog(@"Card is not supporting");
}

Answer 2

在Xcode调试器中运行时，我也有类似的问题。作为解决方法，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。

显然，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。
