It takes too much time to verify all of the receipts when restore purchases about rmstore HOT 2 CLOSED

I assume you're using RMStoreLocalReceiptVerificator.

Simply implement your own RMStoreReceiptVerificator that always validates transactions with state SKPaymentTransactionStateRestored. You can use the code of RMStoreLocalReceiptVerificator for the other transactions.

That said, I find this requirement a bit odd. If you think your users can hack new transactions, then why wouldn't they hack restored transactions as well?

It should be noted that receipt verification takes more time on sandbox because Apple wants you to always try with the production environment first.

Also, transaction notifications are sent for each restored transaction. So you can start updating your UI BEFORE all transactions are restored.
