不，您无法更改它，只需确保在您的应用中使用
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
No you can't change it, just make sure in your App, you use
[[SKPaymentQueue defaultQueue]restoreCompletedTransactions];
还原旧购买的产品，并检查您是否发现用户购买了非消耗性产品(旧用户)，并免费还原该产品.如果用户(新用户)之前没有购买过该产品，请要求他们购买新的自动更新订阅.
Restore old purchase and check if you find that the user has purchased the non-consumable product (old users), restore the product for free. If user has not purchased that product before (new users), ask them to purchase the new auto-renewable subscriptions.
