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
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
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

expressShipping.identifier = @"expressshipping";
expressShipping.detail = @"2-3 小时 送达";
payRequest.shippingMethods = @[freeShipping, expressShipping];
|
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
