“restore purchases”

I have a question about Apple in-app purchases. If a user purchases a non-consumable item that has already been purchased again instead of restoring it, does the same effect as the restoration occur, or does a new payment incur expenses for consumers? The app has a restore button and a process to restore. There are users who sometimes fail to restore, and I am thinking of guiding them to purchase again if the repurchase has the same effect as the restoration.

I have an app with multiple tableview controllers that are displaying their data via core data via a push segue. Each navigation controller and its corresponding tableview controller has 'Restoration ID' string inside of the storyboard.Am I correct in assuming that Xcode does to require a 'restoration class' via code because none of the tableview controllers are created in code? Under which conditions do I need to establish a 'restoration class', like self.restorationClass = [self class];Thank you for your time and response!

HiWe already set up the iTunes Connect for promo codes.There are promocodes that will give you for example (100 gems when you enter this code)But the user enters the promo code when purchasing the app. the app behaves just as it would if it had been purchased.1) My question is how can i determined that he purchased the app using promocode?2) Also how can i restor his transaction that he already used this promo code?What framework should i used.

Hi All,We have two items, both are non-consumable. And to avoid this to be restored in other app account.Upon purchased we grab the receipt from appStoreReceiptURL and send it our server for validation and saving the original_transaction_id for refference, that this item belongs to this user.But, upon restoring purchased the receipt only retrieve the latest item purchase.How can I restore the complete reciept for this app.?First time restoring.{ receipt: { receipt_type: ProductionSandbox, adam_id: 0, app_item_id: 0, bundle_id: com.sample.app, application_version: 1.1.2, download_id: 0, version_external_identifier: 0, receipt_creation_date: 2019-02-18 06:00:50 Etc/GMT, receipt_creation_date_ms: 1550469650000, receipt_creation_date_pst: 2019-02-17 22:00:50 America/Los_Angeles, request_date: 2019-02-19 07:46:15 Etc/GMT, request_date_ms: 1550562375625, request_date_pst: 2019-02-18 23:46:15 America/Los_Angeles, original_purchase_date: 2013-08-01 07:00:00 Etc/GMT, origin

Many our customer are facing a problem on restore process.- They bought several in-app purchase products.- In some case they need to restore products to download contents from Apple server.- We're of course offering restore function in which we use SKPaymentQueue restoreCompletedTransactions.- Restore transaction is finished immediately after customers push the restore button.- From my investigation, paymentQueueRestoreCompletedTransactionsFinished is called, but updatedTransactions is not called.- Actually there is no transaction in the queue when paymentQueueRestoreCompletedTransactionsFinished is called although they have bought products and have a valid receipt.- So there is no transaction to restore, and updatedTransactions is not called. I cannot get any SKDownload objects. That's why we cannot download any contents from Apple server.I spent many days to find a solution in the web, and found many developers had a similar problem with the san
