how list of purchased product ids?

any appreciated...

you can restore purchases using :

[[skpaymentqueue defaultqueue] restorecompletedtransactions];

then skpaymenttransactionobserver call its

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

with skpaymenttransactionstatepurchased transaction state. can see returns array transactions.

can single transaction using,

for (skpaymenttransaction * transaction in transactions) {     nslog(@"purchased indentifier : %@", transaction.payment.productidentifier); }

this print out identifiers user have purchased. can set nsuserdefaults regarding these values
