SKProduct 信息上報可分為 價格、地區(qū)等基礎(chǔ)信息、折扣優(yōu)惠，以下詳細(xì)介紹商品優(yōu)惠信息

優(yōu)惠分為兩種類型

@property(nonatomic, readonly) SKProductDiscountType type API_AVAILABLE(ios(12.2), macos(10.14.4), watchos(6.2));

typedef NS_ENUM(NSUInteger, SKProductDiscountType) {
    SKProductDiscountTypeIntroductory, // 推介優(yōu)惠
    SKProductDiscountTypeSubscription, // 促銷優(yōu)惠
} NS_SWIFT_NAME(SKProductDiscount.Type) API_AVAILABLE(ios(12.2), macos(10.14.4), watchos(6.2));

推介優(yōu)惠

蘋果會根據(jù)該蘋果ID是否享受推介優(yōu)惠，會自動下發(fā)該優(yōu)惠信息，享受過的ID獲取不到推介優(yōu)惠信息，沙盒環(huán)境可以到后臺清除沙盒賬號購買記錄重新購買測試

@property(nonatomic, readonly, nullable) SKProductDiscount *introductoryPrice API_AVAILABLE(ios(11.2), macos(10.13.2), watchos(6.2));

促銷優(yōu)惠

促銷優(yōu)惠為數(shù)組，可以獲取到后臺配置的促銷優(yōu)惠列表

@property(nonatomic, readonly) NSArray<SKProductDiscount *> *discounts API_AVAILABLE(ios(12.2), macos(10.14.4), watchos(6.2));

以上兩種優(yōu)惠都包含以下三種促銷類型

@property(nonatomic, readonly) SKProductDiscountPaymentMode paymentMode API_AVAILABLE(ios(11.2), macos(10.13.2), watchos(6.2));

typedef NS_ENUM(NSUInteger, SKProductDiscountPaymentMode) {
   SKProductDiscountPaymentModePayAsYouGo, // 隨用隨付
   SKProductDiscountPaymentModePayUpFront, // 提前支付
   SKProductDiscountPaymentModeFreeTrial // 免費試用
} NS_SWIFT_NAME(SKProductDiscount.PaymentMode) API_AVAILABLE(ios(11.2), macos(10.13.2), watchos(6.2));

SKProductDiscountPaymentModePayAsYouGo 取周期方式區(qū)別于其他2種優(yōu)惠，需特殊處理
