ios - IAP: Receives `paymentQueueRestoreCompletedTransactionsFinished:` callback with unfinished transactions -


some times callback

- (void)paymentqueuerestorecompletedtransactionsfinished:(skpaymentqueue *)queue

even before receive this

- (void)paymentqueue:(skpaymentqueue *)queue updatedtransactions:(nsarray *)transactions

i don't finishtransaction:. find superweird. i've time been assuming paymentqueuerestorecompletedtransactionsfinished: wouldn't triggered before had marked every unfinished transaction finished.

is expected behavior?

this found in documentation

- (void)paymentqueuerestorecompletedtransactionsfinished:(skpaymentqueue *)queue description tells observer payment queue has finished sending restored transactions. method called after restorable transactions have been processed payment queue. application not required in method.

i'm not sure means.

i found header file clear on part. 

@interface skpaymentqueue : nsobject ... // array of unfinished skpaymenttransactions.  valid while queue has observers.  updated asynchronously. @property(nonatomic, readonly) nsarray *transactions;  @end  @protocol skpaymenttransactionobserver // sent when transactions user's purchase history have been added queue. - (void)paymentqueuerestorecompletedtransactionsfinished:(skpaymentqueue *)queue ... @end

these 2 in conjunction make unambiguous. paymentqueuerestorecompletedtransactionsfinished triggered once storekit has added transactions skpaymentqueue. -[skpaymentqueue transactions] has list of unfinished transactions.

i think docs have been more clear this.
