在iTunes中，免费试用自动续订订阅仅适用于作为报亭应用程序管理的应用程序。如果您创建新应用并将其标记为报刊亭，然后创建自动续订产品，则可以验证这一点。

In iTunes, free trial auto-renewing subscriptions are only available for apps that are managed as newsstand applications. You can verify this if you create a new app and mark it as newsstand and then created an auto-renewing product.

干杯！
