IPhone : In iOS,In app purchase working with development/Ad hoc provision but not working when application on app store

I had developed iOS application,I had successfully implemented in-app purchase on this application.

It looks working perfectly with Development provision as well as Ad hoc provision.

But when I push this build to app store.Apple approve it.However,It not working on live application.

I again push 2 more new versions with minor change but still in-app purchase not working with Production provision (application from app store)

Then after I put error log and can show on my server.I found that I am not getting in-app purchase product from itunes [when application is on app store] which I fetched using following code:

SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers: productIdentifiers];

 request.delegate = self;

[request start];

Here,productIdentifiers are array of my in-app purchase bundle ids.

Though still it working perfectly when i run it on xcode.

What can be reason.Am I miss something?
