so I need to use in-app Purchase with my server, like in http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/APIOverview/OverviewoftheStoreKitAPI.html#//apple_ref/doc/uid/TP40008267-CH100-SW1 example 1-3. Is there any tutorial how to send the data to the server? I've found this http://www.phpriot.com/articles/verifying-app-store-receipts-php-curl but I don't know what I should do in the client thing.
Thanks.
