ApplePayPaymentAuthorizationResult 获取 apple pay for

Apple Pay运行环境：iPhone6以上设备，操作系统最低iOS9.0以上，部分信息设置需要iOS9.2以上。目前还不支持企业证书添加。

环境搭建好后可以在模拟器上面运行，xcode7.2.1+iPhone6SP9.2系统下，系统会绑定几种虚拟的银行卡，和几个联系人，方便调试，支付也不会发生真实的付款，真的很方便。

准备工作

在接入Apple Pay之前，首先要申请MerchantID及对应证书。

请移步我写的申请MerchantID及对应证书详细图文教程

工程设置

bundleID设置

Capability中启用Apple Pay权限，并选择merchantID。

之后项目会多一个Applepay的配置文件ApplePayYasin.entitlements

需要引用的库

Xcode7.0以上不需要再手动添加需要引用的库了，只需要导入头文件就可以了

#import <PassKit/PassKit.h>                                 //用户绑定的银行卡信息  
 #import <PassKit/PKPaymentAuthorizationViewController.h>    //Apple pay的展示控件  
 #import <AddressBook/AddressBook.h>                         //用户联系信息相关

设备Applepay权限检测

if (![PKPaymentAuthorizationViewController class]) {  
         //PKPaymentAuthorizationViewController需iOS8.0以上支持  
         NSLog(@"操作系统不支持ApplePay，请升级至9.0以上版本，且iPhone6以上设备才支持");  
         return;  
     }  
     //检查当前设备是否可以支付  
     if (![PKPaymentAuthorizationViewController canMakePayments]) {  
         //支付需iOS9.0以上支持  
         NSLog(@"设备不支持ApplePay，请升级至9.0以上版本，且iPhone6以上设备才支持");  
         return;  
     }  
     //检查用户是否可进行某种卡的支付，是否支持Amex、MasterCard、Visa与银联四种卡，根据自己项目的需要进行检测  
     NSArray *supportedNetworks = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard,PKPaymentNetworkVisa,PKPaymentNetworkChinaUnionPay];  
     if (![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:supportedNetworks]) {  
         NSLog(@"没有绑定支付卡");  
         return;  
     }

创建支付请求PKPaymentRequest

初始化PKPaymentRequest

这里需要注意RMB的币种代码是CNY

//设置币种、国家码及merchant标识符等基本信息  
   PKPaymentRequest *payRequest = [[PKPaymentRequest alloc]init];  
   payRequest.countryCode = @"CN";     //国家代码  
   payRequest.currencyCode = @"CNY";       //RMB的币种代码  
   payRequest.merchantIdentifier = @"merchant.ApplePayDemoYasin";  //申请的merchantID  
   payRequest.supportedNetworks = supportedNetworks;   //用户可进行支付的银行卡  
   payRequest.merchantCapabilities = PKMerchantCapability3DS|PKMerchantCapabilityEMV;      //设置支持的交易处理协议，3DS必须支持，EMV为可选，目前国内的话还是使用两者吧

设置发票配送信息和货物配送地址信息,用户设置后可以通过代理回调代理获取信息的更新

//    payRequest.requiredBillingAddressFields = PKAddressFieldEmail;     
 //如果需要邮寄账单可以选择进行设置，默认PKAddressFieldNone(不邮寄账单)  
 //楼主感觉账单邮寄地址可以事先让用户选择是否需要，否则会增加客户的输入麻烦度，体验不好，  
   payRequest.requiredShippingAddressFields = PKAddressFieldPostalAddress|PKAddressFieldPhone|PKAddressFieldName;  
   //送货地址信息，这里设置需要地址和联系方式和姓名，如果需要进行设置，默认PKAddressFieldNone(没有送货地址)

送货信息页面展示

设置货物的配送方式，不需要不配置

//设置两种配送方式  
   PKShippingMethod *freeShipping = [PKShippingMethod summaryItemWithLabel:@"包邮" amount:[NSDecimalNumber zero]];  
   freeShipping.identifier = @"freeshipping";  
   freeShipping.detail = @"6-8 天 送达";  

   PKShippingMethod *expressShipping = [PKShippingMethod summaryItemWithLabel:@"极速送达" amount:[NSDecimalNumber decimalNumberWithString:@"10.00"]];  
   expressShipping.identifier = @"expressshipping";  
   expressShipping.detail = @"2-3 小时 送达";  

   payRequest.shippingMethods = @[freeShipping, expressShipping];

账单信息的设置

每条账单的设置

账单列表使用PKPaymentSummaryItem添加描述和价格，价格使用NSDecimalNumber。

PKPaymentSummaryItem初始化：

label为商品名字或者是描述，amount为商品价格，折扣为负数，type为该条账单为最终价格还是估算价格(比如出租车价格预估)

+ (instancetype)summaryItemWithLabel:(NSString *)label amount:(NSDecimalNumber *)amount;  
 + (instancetype)summaryItemWithLabel:(NSString *)label amount:(NSDecimalNumber *)amount type:(PKPaymentSummaryItemType)type NS_AVAILABLE(NA, 9_0);

NSDecimalNumber初始化：

NSDecimalNumber可以使用数字初始化，也可以使用字符串。

使用方法请移步我写的NSDecimalNumber--十进制数

添加账单列表：

NSDecimalNumber *subtotalAmount = [NSDecimalNumber decimalNumberWithMantissa:1275 exponent:-2 isNegative:NO];   //12.75  
 PKPaymentSummaryItem *subtotal = [PKPaymentSummaryItem summaryItemWithLabel:@"商品价格" amount:subtotalAmount];  

 NSDecimalNumber *discountAmount = [NSDecimalNumber decimalNumberWithString:@"-12.74"];      //-12.74  
 PKPaymentSummaryItem *discount = [PKPaymentSummaryItem summaryItemWithLabel:@"优惠折扣" amount:discountAmount];  

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

 NSDecimalNumber *totalAmount = [NSDecimalNumber zero];  
 totalAmount = [totalAmount decimalNumberByAdding:subtotalAmount];  
 totalAmount = [totalAmount decimalNumberByAdding:discountAmount];  
 totalAmount = [totalAmount decimalNumberByAdding:methodsAmount];  
 PKPaymentSummaryItem *total = [PKPaymentSummaryItem summaryItemWithLabel:@"Yasin" amount:totalAmount];  //最后这个是支付给谁。哈哈，快支付给我  

 summaryItems = [NSMutableArray arrayWithArray:@[subtotal, discount, methods, total]];  
 //summaryItems为账单列表，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支付金额的调整。  
 payRequest.paymentSummaryItems = summaryItems;

显示购物信息并进行支付

//ApplePay控件  
     PKPaymentAuthorizationViewController *view = [[PKPaymentAuthorizationViewController alloc]initWithPaymentRequest:payRequest];  
     view.delegate = self;  
     [self presentViewController:view animated:YES completion:nil];  

 PKPaymentAuthorizationViewControllerDelegate代理

这里还有两个类要介绍

PKPayment 支付成功信息

PKPaymentToken *payToken = payment.token;  
 //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

PKContact 联系人信息

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;  //补充信息，地址详细描述，其他备注等等,iOS9.2及以上才有

代理说明

送货地址回调

送货方式回调

-(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  
   //送货信息选择回调，如果需要根据送货地址调整送货方式，比如普通地区包邮+极速配送，偏远地区只有付费普通配送，进行支付金额重新计算，可以实现该代理，返回给系统：shippingMethods配送方式，summaryItems账单列表，如果不支持该送货信息返回想要的PKPaymentAuthorizationStatus  
   completion(PKPaymentAuthorizationStatusSuccess, shippingMethods, summaryItems);  
 }

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

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

   completion(PKPaymentAuthorizationStatusSuccess, summaryItems);  
 }  total.amount = [total.amount decimalNumberByAdding:shippingMethod.amount];  

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

   completion(PKPaymentAuthorizationStatusSuccess, summaryItems);  
 }

支付卡选择回调

-(void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didSelectPaymentMethod:(PKPaymentMethod *)paymentMethod completion:(void (^)(NSArray<PKPaymentSummaryItem *> * _Nonnull))completion{  
   //支付银行卡回调，如果需要根据不同的银行调整付费金额，可以实现该代理  
   completion(summaryItems);  
 }

送货地址回调，已弃用

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

付款成功苹果服务器返回信息回调，做服务器验证

-(void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller  
                      didAuthorizePayment:(PKPayment *)payment  
                               completion:(void (^)(PKPaymentAuthorizationStatus status))completion {  
   PKPaymentToken *payToken = payment.token;  
   //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);  
   });  
 }

支付完成回调

-(void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller{  
   [controller dismissViewControllerAnimated:YES completion:nil];  
 }
