We found that while your app offers In-App Purchase(s) that can be restored, it does not include the required "Restore" feature to allow users to restore the previously purchased In-App Purchase(s), as specified in Restoring Transactions section of the In-App Purchase Programming Guide:

"...if your application supports product types that must be restorable, you must include an interface that allows users to restore these purchases. This interface allows a user to add the product to other devices or, if the original device was wiped, to restore the transaction on the original device."

To restore previously purchased In-App Purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped by the user.

For more information about restoring transactions and verifying store receipt, please refer to the In-App Purchase Programming Guide.

解決方法很簡(jiǎn)單，增加一個(gè)Restore按鈕，并調(diào)用[[SKPaymentQueue defaultQueue] restoreCompletedTransactions]，接下來(lái)的流程是

1，彈出對(duì)話(huà)框輸入賬號(hào)信息
2，如果點(diǎn)擊“取消”，調(diào)用方法
-(void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error
如果點(diǎn)擊“確定”，開(kāi)始請(qǐng)求數(shù)據(jù)
3,返回?cái)?shù)據(jù)后，回調(diào)
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
4,判斷交易隊(duì)列中交易的狀態(tài)，在狀態(tài)為“SKPaymentTransactionStateRestored”的switch分支下調(diào)用恢復(fù)處理方法
5,恢復(fù)完成后回調(diào)-(void)completeTransaction:(SKPaymentTransaction *)transaction
