ios - PKPaymentAuthorizationViewController 在 iOS 8.4 上意外崩溃

Question

背景:我在 iOS 8.2、8.3 上使用了相同的代码，它们运行良好。

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，当我尝试显示我的 paymentPane 时，它​​的值不知何故为零。

Fatal Exception: NSInvalidArgumentException Application tried to present a nil modal view controller on target .

我已经通过谷歌搜索和使用来自 stackoverflow 的答案进行了尝试。

• 使用支票喜欢

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

  和

  [PKPaymentAuthorizationViewController canMakePayments]

• 正在检查我的商家 ID 是否有效。

• 正在检查我用于请求的所有代码是否有效。

Answer 1

1. 检查你是否添加了Credit card您设备中的信息 Passbook还是不是。

2. 检查您是否可以使用您的设备进行支付。
   
   Objective-C :

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

   swift :

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

3. 检查您是否可以使用允许的 payment networks 进行付款.
   
   Objective-C : <pre>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");
}</pre> swift : <pre>let paymentNetworks = [PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa]
if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(paymentNetworks) {
    NSLog(@"Can Make payment with your card");
}
else {
    NSLog(@"Card is not supporting");
}</pre>
