我是靠谱客的博主潇洒香水，最近开发中收集的这篇文章主要介绍ios Apple Pay 简单使用，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

配置
1.在开发者帐号中先添加一个 Merchant IDs
2.如果已经有apple id，编辑apple id 在其中打开apple pay 选项，这时候就可选择刚才添加的 Merchant IDs
3.重新配置provisioning Profiles安装
4.在工程文件选择capatilities 大家app pay选项，然后程序就会自动关联之前设置的 Merchant IDs
5.在程序中导入头文件#import<PassKit/PassKit.h>
同时要遵守一个协议<PKPaymentAuthorizationViewControllerDelegate>
6.代码实现部分

if([PKPaymentAuthorizationViewController canMakePayments])
    {
        NSLog(@"设备支持支付");

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

        PKPaymentSummaryItem *item1 = [PKPaymentSummaryItem summaryItemWithLabel:@"Widget1" amount:[NSDecimalNumber decimalNumberWithString:@"0.01"]];

        PKPaymentSummaryItem *item2 = [PKPaymentSummaryItem summaryItemWithLabel:@"Widget2" amount:[NSDecimalNumber decimalNumberWithString:@"0.01"]];

        PKPaymentSummaryItem *total = [PKPaymentSummaryItem summaryItemWithLabel:@"Grand Total" amount:[NSDecimalNumber decimalNumberWithString:@"0.02"]];


        request.paymentSummaryItems = @[item1,item2,total]; // 最后一个必须是总价格
        request.countryCode = @"CN"; // 国家
        request.currencyCode = @"CNY"; // 人民币

        request.supportedNetworks =@[PKPaymentNetworkChinaUnionPay,PKPaymentNetworkAmex,PKPaymentNetworkDiscover,PKPaymentNetworkInterac, PKPaymentNetworkMasterCard,PKPaymentNetworkPrivateLabel,PKPaymentNetworkVisa];

        request.merchantIdentifier = @"merchant.com.testapa";
        request.merchantCapabilities = PKMerchantCapability3DS|PKMerchantCapabilityEMV;

        PKPaymentAuthorizationViewController *payvw = [[PKPaymentAuthorizationViewController alloc]initWithPaymentRequest:request];

        if (payvw) {

            payvw.delegate = self;

            [self presentViewController:payvw animated:YES completion:nil];

        }else
        {

            UIAlertView *alertView=[[UIAlertView alloc] initWithTitle:nil message:@"n未绑定卡n" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
            [alertView show];

        }



    }else
    {

        UIAlertView *alertView=[[UIAlertView alloc] initWithTitle:nil message:@"n此设备不支持apple payn" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alertView show];
        NSLog(@"此设备不支持apple pay");
    }
7.实现协议以及回处理

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didAuthorizePayment:(PKPayment *)payment completion:(void (^)(PKPaymentAuthorizationStatus))completion
{


    NSLog(@"payment was authoried %@ ",payment);

    PKPaymentToken *payToken = payment.token;

    NSLog(@"token = %@ ",payToken);

    //支付凭据，发给服务端进行验证支付是否真实有效
//    PKContact *billingContact = payment.billingContact;     //账单信息
//    PKContact *shippingContact = payment.shippingContact;   //送货信息
//    PKContact *shippingMethod = payment.shippingMethod;     //送货方式
    //等待服务器返回结果后再进行系统block调用
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        //模拟服务器通信
        completion(PKPaymentAuthorizationStatusSuccess);
    });


}

- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller
{

    NSLog(@"Finishing payment view controller");
    [controller dismissViewControllerAnimated:TRUE completion:nil];

}
8.付款成功后会返回一个token发送给服务器，服务器在收到 App 发送来的支付信息后，对数据进行解密操作，提取其中需要的信息，组织银联接口报文，调用银联的接口，完成扣款，会回调验证结果
9.要保证你的手机已经绑定了银行卡，如果没有去设置-Wallet与Apple Pay 绑定
否则可能会出现This device cannot make payments错误
