ios - Using appStoreReceiptURL to restore non-renewing subscription

Question

I can use the receipt obtained by appStoreReceiptURL to retrieve the purchase date of non-renewing subscription. For non-renewing subscription, from the purchase date I could calculate the expiration date.

But when I try to restore using appStoreReceiptURL. I found that it returns nil on devices that did not make purchase even signing in with the same Apple ID.

Using

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

cannot update the receipts in appStoreReceiptURL. Did I do anything wrong here? Or is it just not possible to restore the receipts this way?

Thanks

您无法以您尝试的方式恢复事务，因为它们是消耗品，并且消耗品具有有限的寿命。

但是，您可以解析收据，并据此计算订阅期。

收据将在主捆绑包中，但可以使用刷新

recreq = [[SKReceiptRefreshRequest alloc] init];
        [recreq setDelegate:self];
        [recreq start];
