Question

ios开发 xcode7 怎么在capability中启用apple pay

Answer 1

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</addressbook></passkit></passkit>

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

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;

//ApplePay控件

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

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

demo的话因为证书问题可能会报错，不过大家可以看看代码。
