SKPaymentTransaction: what is a transaction?

The Apple transactionDate documentation has:

The date the transaction was added to the App Store payment queue. (Only for reading)

I just want to clarify what transactionDate will do in the following case:

  • bought something during T1 (transactionDate - T1?)
  • restored purchase at time T2 (transactionDate - T2 or T1?)
  • originalTransaction of the restored transaction, is its transaction T1 or T2?

Thanks!

  • bought something during T1 (transactionDate - T1?)

Yes. transactionDate - T1. The following documentation for the apple:

transactionDate: The date the transaction was added to the App Store payment queue.

  1. restored purchase at time T2 (transactionDate - T2 or T1?)

Irrelevant. If transactionState set to SKPaymentTransactionStateRestored , you should read originalTransaction . The following documentation for the apple:

originalTransaction: The contents of this property are undefined, unless TransactionState is set to SKPaymentTransactionStateRestored. When a transaction is restored, the current transaction contains a new transaction identifier, receipt, etc. Your application will read this property to restore the restored transaction.

  1. originalTransaction of the restored transaction, is its transaction T1 or T2?

T1.

1) if transactionState SKPaymentTransactionStatePurchased transactionDate is always T1

2) if transactionState is SKPaymentTransactionStateRestored transactionDate is T2 or T3 (recovery date)

3) originalTransaction.transactionDate is always T1
