Hello.
I tested it in a sandbox environment yesterday.
Suddenly this morning In App Purchase system does not work.
I don't know Why this problem happen.
It was the same with the old code.
I tested until yesterday, submitted a binary app to the App Store, and the app is approved.
I tested before distributing my app, but In-app Purchase did not work.
NSSet* productIdentifier = [NSSet setWithObject:productIdentifiers.productCode];
SKProductsRequest *productsRequest = [[SKProductsRequest alloc]initWithProductIdentifiers:productIdentifier];
productsRequest.delegate = self;
[productsRequest start];
and..
- (void) productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
never called... No error any response... No....
