PKPaymentAuthorizationViewController在iOS 8.4上意外崩溃 [英] PKPaymentAuthorizationViewController is crashing unexpectedly on iOS 8.4

问题描述

后台：我在iOS 8.2,8.3上使用了相同的代码，但它运行正常。

Background: I used same code for iOS 8.2,8.3 it was working fine.

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：现在我在iOS 8.4上尝试展示我的payPane价值是以某种方式为零。

Question: Now on iOS 8.4 when I try to present my paymentPane its value is nil somehow.

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

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

我已经尝试使用Google搜索和使用stackoverflow的答案。

• 二手支票

• Used Checks like

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

和

[PKPaymentAuthorizationViewController canMakePayments]

检查我的商家ID是否有效。

Checking my merchant id is valid or not.

推荐答案

1. 检查磨她已经在您的设备中添加了信用卡信息 Passbook 。

检查您是否可以使用自己的设备付款。


目标C：

Check whether you can make payment using your device.

Objective C :

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

Swift：

Swift :

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");
}

Swift：

Swift :

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