StoreKit

• 用于iOS内购

内购流程

• 配置一个明确的APPID

• 配置内购相关的内容

  • 配置内购项 配置测试账号 配置银行 信息

• 内购的流程

• 内购代码的实现

  • 获取想卖的商品的ProductID(服务器)—>NSSet
  • 请求可买的商品(SKProductRequest)
  • 代理方法:SKProductResponse—>products—>SKProduct
  • SKPayment paymentWithProduct:product
  • [SKPaymentQueue defaultQueue] addPayment:payment
  • [添加观察者]
  • SKPaymentTransaction—>transactionState
  • [SKPaymentQueue defaultQueue] retoreTransactions
