thanks aditya

hi prompt reply.i have implemented same have suggested.what i'm wondering if delete app , install again , asked purchase again.do have pay again upgrade or handled apple server(i.e if upgrade same product again charged again?).is there way know upgraded without asking upgrade again?

the storekit api takes care of , gives you, on request, list of identifiers of purchased items. once got those, it's re-download products again(if not bundled inside app).

excerpt storekit api help:

-(void)restorecompletedtransactions

asks payment queue restore completed purchases.

your application calls method restore transactions finished can process them again. example, application use allow user unlock purchased content onto new device.

when create new product sold in store, choose whether product can restored or not. see in app purchase programming guide more information.

the payment queue deliver new transaction each completed transaction can restored. each transaction includes copy of original transaction.
