ios - StoreKit framework 2 questions -

just getting started store kit framework. have 2 questions:

1) there way find out purchased items current user? (get list of ids) 2) there way purchase items? or have prompt user each , every one?

thanks

there way find out purchased items calling [[skpaymentqueue defaultqueue] restorecompletedtransactions];

then

-(void)paymentqueue:(skpaymentqueue *)queue updatedtransactions:(nsarray *)transactions{  (skpaymenttransaction * transaction in transactions) {     switch (transaction.transactionstate)     {         case skpaymenttransactionstatepurchased:   break;    case skpaymenttransactionstaterestored: 

// info item transaction.originaltransaction.payment.productidentifier

            [[skpaymentqueue defaultqueue] finishtransaction:transaction];             break;           case skpaymenttransactionstatefailed:     break;          case skpaymenttransactionstatepurchasing:      break;          default:               break; } } 

}

2) if can tell user possible buy items 1 click. user asked purchase each item separately.
