最近一个特别火的词组出现在我们的生活中Apple Pay，大家又对其了解多少呢？其实在 iOS8.1 之后 Apple Pay 功能已经开放了，只不过在大陆在今年 2 月才可以使用，Apple Pay 是一个基于 NFC 的支付系统，类似于你的银行卡，走到哪刷到哪，那么作为开发人员的我们该如何去开发和使用呢？

1、我们要去设置Merchant IDs

Merchat IDs 设置

在设置 Identifier 的时候要注意 ID 的格式

Merchat IDs identifier 设置

注册成功以后

Choose File

从证书颁发机构请求证书

2、到目前为止我们的基本设置已经设置好了，现在我们要去Xcode里面去配置相关信息

由于我们要在真机上测试，所以我们要选择描述文件

3、代码示范

遵循PKPaymentAuthorizationViewControllerDelegate

#pragma mark ----支付状态
- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
                       didAuthorizePayment:(PKPayment *)payment
                                completion:(void (^)(PKPaymentAuthorizationStatus status))completion
{
    NSLog(@"花费: %@", payment);

    BOOL asyncSuccessful = FALSE;
    if(asyncSuccessful) {
        completion(PKPaymentAuthorizationStatusSuccess);

        NSLog(@"支付成功");

    } else {
        completion(PKPaymentAuthorizationStatusFailure);

        NSLog(@"支付失败");
    }
}

#pragma mark ----支付完成
- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller {

    // 支付完成后让支付页面消失
    [controller dismissViewControllerAnimated:YES completion:nil];
}

支付方法

#pragma mark -----点击支付
- (IBAction)checkOut:(id)sender
{
    if([PKPaymentAuthorizationViewController canMakePayments]) {

        NSLog(@"支持支付");

        // 我们后面创建出来的支付页面就是根据这个request
        PKPaymentRequest *request = [[PKPaymentRequest alloc] init];
        // 商品目录
        PKPaymentSummaryItem *widget1 = [PKPaymentSummaryItem summaryItemWithLabel:@"大展"
                                                                            amount:[NSDecimalNumber decimalNumberWithString:@"0.01"]];

        PKPaymentSummaryItem *widget2 = [PKPaymentSummaryItem summaryItemWithLabel:@"小展"
                                                                            amount:[NSDecimalNumber decimalNumberWithString:@"0.01"]];

        PKPaymentSummaryItem *widget3 = [PKPaymentSummaryItem summaryItemWithLabel:@"2个大展"
                                                                            amount:[NSDecimalNumber decimalNumberWithString:@"0.02"]];

        PKPaymentSummaryItem *widget4 = [PKPaymentSummaryItem summaryItemWithLabel:@"总金额" amount:[NSDecimalNumber decimalNumberWithString:@"0.01"] type:PKPaymentSummaryItemTypeFinal];

        request.paymentSummaryItems = @[widget1, widget2, widget3, widget4];
        request.countryCode = @"CN";
        request.currencyCode = @"CNY";//人民币
        request.supportedNetworks = @[PKPaymentNetworkChinaUnionPay, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];

        // 这里填的是就是我们创建的merchat IDs
        request.merchantIdentifier = @"merchant.com.dazhan.applePayDemo";
        request.merchantCapabilities = PKMerchantCapabilityCredit;
        //增加邮箱及地址信息
        request.requiredBillingAddressFields = PKAddressFieldEmail | PKAddressFieldPostalAddress;

        // 根据request去创建支付页面
        PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];

        // 设置代理
        paymentPane.delegate = self;

        if (!paymentPane) {

            NSLog(@"出问题了");
        } else {

            // 模态推出页面
            [self presentViewController:paymentPane animated:YES         completion:nil];
        }     
    } else {

        NSLog(@"该设备不支持支付");
    }
}
