ApplePay 支付的简单使用

ApplePay支付功能出来已经很久了，看着API自己学习了一下，今天想起来总结一下，也算是在学习一下，所以写了这篇笔记，

applePay是在iphone 6以上设备才支持这个支付功能的，这一点一定要清楚，
我是简单的实现了一下功能做演示功能其他的就不说了，直接上代码，加注释

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    //判断设备是否支持applePay功能
    if (![PKPaymentAuthorizationViewController canMakePayments]) {
        //设备不支持
        //不让applePay的支付按钮显示
        NSLog(@"设备不支持");

        return;
    }
    //判断是否支持Visa和银联
    if (![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:@[PKPaymentNetworkChinaUnionPay,PKPaymentNetworkVisa]]) {

        NSLog(@"支持visa和银联");
        //进入银行卡的选择
        [[[PKPassLibrary alloc]init]openPaymentSetup];


        return;
    }

    //创建支付请求
    PKPaymentRequest *requ = [[PKPaymentRequest alloc]init];

    //设置商户ID。这个ID就是和支付宝的商户ID意思一样
    requ.merchantIdentifier = @"merchant.www.Kensence.com.ApplePay";

    //设置国家代码
    requ.countryCode = @"CN"; //表示中国

    //设置支持卡
    requ.supportedNetworks = @[PKPaymentNetworkChinaUnionPay,PKPaymentNetworkVisa];
    //商户的支付标准
    requ.merchantCapabilities = PKMerchantCapability3DS;
    //设置货币单位
    requ.currencyCode = @"CNY";

    //设置商品
    NSDecimalNumber *number = [NSDecimalNumber decimalNumberWithString:@"4"];

    PKPaymentSummaryItem *item = [PKPaymentSummaryItem summaryItemWithLabel:@"毛巾" amount:number];

    //多种商品最后一个item是商品的总价，这个一定要搞清楚，最后一个应该传商品的总价，
    requ.paymentSummaryItems = @[item];

    //设置收据必填内容
    requ.requiredBillingAddressFields = PKAddressFieldAll;

    //设置送货地址
    requ.requiredShippingAddressFields = PKAddressFieldAll;


    //设置送货方式
    PKShippingMethod *meth = [PKShippingMethod summaryItemWithLabel:@"顺风" amount:[NSDecimalNumber decimalNumberWithString:@"8"]];

    meth.identifier = @"shunfeng";
    meth.detail =  @"24小时之内到达";


    requ.shippingMethods = @[meth];




    //显示支付界面
    PKPaymentAuthorizationViewController *payVC = [[PKPaymentAuthorizationViewController alloc]initWithPaymentRequest:requ];
    payVC.delegate = self;

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


}

//使用密码支付
- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
                       didAuthorizePayment:(PKPayment *)payment
                                completion:(void (^)(PKPaymentAuthorizationStatus status))completion

{
    //把支付信息发送给服务器处理

    //支付结果，显示不同的显示（调用block，穿不同的枚举）
    completion(PKPaymentAuthorizationStatusSuccess);


}

- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller
{
    //把支付的界面关闭
    [self dismissViewControllerAnimated:YES completion:nil];

}
