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。
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

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) |

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
