The StoreKit framework allows you to restore purchases for users without having to pay multiple times for a purchase. StoreKit框架允许您为用户恢复购买，而无需为购买多次付款。

Look at the Store Kit documentation for Restoring Transactions. 查看还原事务的Store Kit文档。

The restoration process requires the user to log in with their iTunes Account, so that the system knows their purchase history. 恢复过程要求用户使用其iTunes帐户登录，以便系统知道他们的购买历史记录。

As long as you implement the restore process and provide a UI for a user to do so, you users should never have to pay more than once for a purchase within your app, even if they uninstall the app and reinstall it on a different device. 只要您实施还原过程并为用户提供用户界面，用户就不应该为应用内的购买付费多次，即使他们卸载应用并在其他设备上重新安装也是如此。
