IAP storekit1答疑

在用苹果IAP进行内购时常见疑惑答疑，都是自己摸索的如有错误请评论告知

首先我们都知道在storekit1中我们需要上传receipt(票据)让服务端去苹果后台验证是否是有效的票据，如果是给用户发放相应的权益，解析的票据见文章末尾。

疑问一： in_app:[] 和 latest_receipt_info:[] 中的数据数目为什么不一致，为什么有时候latest_receipt_info 比 in_app 中的数量多

答： 如果你的 in_app 中的数据比latest_receipt_info中的数量少，那是因为你当前传给苹果的票据不是最新的票据，可以尝试用latest_receipt重新请求一遍就可以看到两者数目数量是一致的了。经过我的测试我发现latest_receipt_info[].count > in_app [].count

疑问二：为什么 pending_renewal_info 中的 auto_renew_product_id 和 product_id 不一致

答：我们知道 pending_renewal_info 代表的是下个续费周期订阅的产品，特别是切换套餐时就会出现和我们当前已经订阅的套餐不一致的情况。

product_id代表的是切换前的套餐
auto_renew_product_id代表的切换后的套餐
疑问三：StoreKit 沙盒模式下订阅已订阅的订阅就会弹出以下弹框

public func paymentQueue(_ queue: SKPaymentQueue,updatedTransactions transactions: [SKPaymentTransaction])

答：暂时无解，建议做成和苹果一样，订阅成功后把该项隐藏掉或者不可点击。哪位大佬知道其他办法可以评论一下，感谢
