Apple Pay开发-项目集成-详细设置

今天公司的 WeChatpay and QQWallet 迎来了新的兄弟：Apple Pay

o(╯□╰)o好累啊，都说好不做钱包支付的，结果还是硬做了。

ps:确实比蓝牙控制机器人好做



简单介绍一下：2月18日，苹果公司移动支付服务Apple Pay正式登陆中国。 Apple
Pay是苹果公司在2014年发布的一种基于NFC（近距离无线通信）技术的移动支付服务。

话不多说啦，进入正题：

①Apple Pay运行环境：操作系统最低iOS9.0以上，iPhone6以上设备。

②用开发者账号申请MerchantID和证书

③开始创建工程并设置：

起名的时候随意，但是要记住的是你的证书和你的bundleID是要对应的

然后在Capability开启Apple
Pay（如图）



然后工程中会有配置文件Japan-ApplePay.entitlements



然后开始添加framework



工程配置完了，现在开始进入码代码阶段，直接进入ViewController.m



接下来就是开始写相应内容：

创建两个属性：

<span style="font-size:14px;">@property (nonatomic)NSMutableArray * accountlist;// 账户的账单
@property (nonatomic)NSMutableArray * shopway;// 购买的方式</span>

写一个判断方法：

<span style="font-size:14px;">// 开始之前对设备进行判断
- (BOOL)AccessApplePay
{
// 判断当前设备支持支付或否
if (![PKPaymentAuthorizationViewController class]) {
// 为No的时候，主要是系统不支持，需要在9.0的环境以及iphone6以上机型
return NO;
}
if (![PKPaymentAuthorizationViewController canMakePayments]) {
// 原因同上
return NO;
}

// 判断用户是否可进行四种卡片的支付，分别是Amex、MasterCard、Visa与Union四种卡
NSArray *cardkind = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard,PKPaymentNetworkVisa,PKPaymentNetworkChinaUnionPay];
// 下面这步判断的是有没有绑定银行卡
if (![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:cardkind]) {
NSLog(@"没有绑定卡");
return NO;
}

NSLog(@"判断完成");
return YES;
}</span><span style="font-size: 14px;">
</span>

在判断方法结束之后执行这个：

<span style="font-size:14px;">// 对手机进行判定以后开始支付流程
if ([self AccessApplePay]) {
[self BeginProcess];
}</span>

已经很详细的设置了每一个参数

<span style="font-size:14px;">// 达到允许条件之后开始进入流程
- (void)BeginProcess
{
// 支付卡片的四种选项
NSArray *cardkind = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard,PKPaymentNetworkVisa,PKPaymentNetworkChinaUnionPay];

// 设置基本信息
PKPaymentRequest *payRequest = [[PKPaymentRequest alloc]init];
payRequest.countryCode = @"CN";         // 国家代码
payRequest.currencyCode = @"CNY";       // 币种

payRequest.merchantIdentifier = @"merchant.Japan-ApplePay";   // 申请的merchantID
payRequest.supportedNetworks = cardkind;                      // 用于支付的卡的种类

payRequest.merchantCapabilities = PKMerchantCapability3DS|PKMerchantCapabilityEMV;  // 设置支持的交易处理协议

payRequest.requiredShippingAddressFields = PKAddressFieldPostalAddress|PKAddressFieldPhone|PKAddressFieldName;  // 送货的信息，设置地址，电话，姓名

// 设置送货方式
// 免费的快递
PKShippingMethod *freeShipping = [PKShippingMethod summaryItemWithLabel:@"EMS包邮" amount:[NSDecimalNumber zero]];
freeShipping.identifier = @"freeshipping";
freeShipping.detail = @"4-6 天";
// 需要加钱的快递
PKShippingMethod *expressShipping = [PKShippingMethod summaryItemWithLabel:@"顺丰速运" amount:[NSDecimalNumber decimalNumberWithString:@"10.00"]];
expressShipping.identifier = @"expressshipping";
expressShipping.detail = @"2-3 天";
// 在这里使用到了_shopway的数组
_shopway = [NSMutableArray arrayWithArray:@[freeShipping, expressShipping]];
//shippingMethods为配送方式列表，类型是 NSMutableArray，这里设置成成员变量，在后续的代理回调中可以进行配送方式的调整。
payRequest.shippingMethods = _shopway;

NSDecimalNumber *subtotalAmount = [NSDecimalNumber decimalNumberWithMantissa:10000 exponent:-2 isNegative:NO];// 小数点后两位1000.00
PKPaymentSummaryItem *subtotal = [PKPaymentSummaryItem summaryItemWithLabel:@"商品价格" amount:subtotalAmount];

NSDecimalNumber *discountAmount = [NSDecimalNumber decimalNumberWithString:@"-10"];      // 折扣10
PKPaymentSummaryItem *discount = [PKPaymentSummaryItem summaryItemWithLabel:@"折扣" amount:discountAmount];

NSDecimalNumber *methodsAmount = [NSDecimalNumber zero];
PKPaymentSummaryItem *methods = [PKPaymentSummaryItem summaryItemWithLabel:@"EMS包邮" amount:methodsAmount];

NSDecimalNumber *totalAmount = [NSDecimalNumber zero];
totalAmount = [totalAmount decimalNumberByAdding:subtotalAmount];
totalAmount = [totalAmount decimalNumberByAdding:discountAmount];
totalAmount = [totalAmount decimalNumberByAdding:methodsAmount];
PKPaymentSummaryItem *total = [PKPaymentSummaryItem summaryItemWithLabel:@"喵喵的账户~" amount:totalAmount];// 收款方名字，账户
_accountlist = [NSMutableArray arrayWithArray:@[subtotal, discount, methods, total]];
//_accountlist是存放账单的可变数组，后续的代理中可以进行支付金额的调整。
payRequest.paymentSummaryItems = _accountlist;

// 启用ApplePay的页面控件
PKPaymentAuthorizationViewController *view = [[PKPaymentAuthorizationViewController alloc]initWithPaymentRequest:payRequest];
view.delegate = self;
[self presentViewController:view animated:YES completion:nil];
}</span><span style="font-size: 14px;">
</span>

最后不要忘记协议代理：

<span style="font-size:14px;">#pragma mark 支付的代理设置
- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
didSelectShippingContact:(PKContact *)contact
completion:(void (^)(PKPaymentAuthorizationStatus, NSArray<PKShippingMethod *> * _Nonnull, NSArray<PKPaymentSummaryItem *> * _Nonnull))completion{
//contact送货地址信息，PKContact类型
NSPersonNameComponents *name = contact.name;                //联系人 姓名
CNPostalAddress *postalAddress = contact.postalAddress;     //联系人 地址
NSString *emailAddress = contact.emailAddress;              //联系人 邮箱
CNPhoneNumber *phoneNumber = contact.phoneNumber;           //联系人 手机
NSString *supplementarySubLocality = contact.supplementarySubLocality;

completion(PKPaymentAuthorizationStatusSuccess, _shopway, _accountlist);
}

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
didSelectShippingMethod:(PKShippingMethod *)shippingMethod
completion:(void (^)(PKPaymentAuthorizationStatus, NSArray<PKPaymentSummaryItem *> * _Nonnull))completion{
// 送货方式回调，如果需要根据不同的送货方式进行支付金额的调整，比如EMS包邮和付费顺丰配送，可以实现该代理
PKShippingMethod *oldShippingMethod = [_accountlist objectAtIndex:2];
PKPaymentSummaryItem *total = [_accountlist lastObject];
total.amount = [total.amount decimalNumberBySubtracting:oldShippingMethod.amount];
total.amount = [total.amount decimalNumberByAdding:shippingMethod.amount];

[_accountlist replaceObjectAtIndex:2 withObject:shippingMethod];
[_accountlist replaceObjectAtIndex:3 withObject:total];

completion(PKPaymentAuthorizationStatusSuccess, _accountlist);
}

// 支付银行卡回调，看情况根据不同的银行调整，然后付费金额
-(void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didSelectPaymentMethod:(PKPaymentMethod *)paymentMethod completion:(void (^)(NSArray<PKPaymentSummaryItem *> * _Nonnull))completion{

completion(_accountlist);
}

// 送货地址的回调
-(void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didSelectShippingAddress:(ABRecordRef)address completion:(void (^)(PKPaymentAuthorizationStatus, NSArray<PKShippingMethod *> * _Nonnull, NSArray<PKPaymentSummaryItem *> * _Nonnull))completion{

}

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
didAuthorizePayment:(PKPayment *)payment
completion:(void (^)(PKPaymentAuthorizationStatus status))completion {
// 支付验证
PKPaymentToken *payToken = payment.token; // 与服务器验证支付是否有效

PKContact *billingContact = payment.billingContact;     //账单信息
PKContact *shippingContact = payment.shippingContact;   //送货信息
PKContact *shippingMethod = payment.shippingMethod;     //送货方式

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

completion(PKPaymentAuthorizationStatusSuccess);
});

}
- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller{
[controller dismissViewControllerAnimated:YES completion:nil];
}</span><span style="font-size:18px;">
</span>

然后我们就可以运行了~效果如下：
