In App Purchase SKProductsRequest does not work when the application is already installed on the device

Question

I'm having problems testing the app purchase feature. If I reinstall the application on a device that already installed the application with the previous version, SKProductsRequest returns a response with only an object to invalidProductIdentifiers. If I remove the application from the device and then reinstall the new version, SKProductsRequest works fine.

Any ideas?

Thanks in advance.

- (void)requestProductData:(NSString *)aFeatureID { SLLog(@"Products Request For: %@", aFeatureID); SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:aFeatureID]]; request.delegate = self; [request start]; } - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { if ([response.products count] > 0) { [self.purchasableObjects addObjectsFromArray:response.products]; #ifndef NDEBUG for(int i=0;i<[self.purchasableObjects count];i++) { SKProduct *product = [self.purchasableObjects objectAtIndex:i]; SLLog(@"Feature: %@, Cost: %f, ID: %@",[product localizedTitle], [[product price] doubleValue], [product productIdentifier]); } for(NSString *invalidProduct in response.invalidProductIdentifiers) SLLog(@"Problem in iTunes connect configuration for product: %@", invalidProduct); #endif isProductsAvailable = YES; } else if ([response.invalidProductIdentifiers count] > 0){ SLLog(@"MKStoreManager-productsRequest empty results: %@", [response.invalidProductIdentifiers objectAtIndex:0]); } if([_delegate respondsToSelector:@selector(productFetchComplete)]) [_delegate productFetchComplete]; [request autorelease]; }

This is what someone told me on Cocoa [e-mail] :

Are you connecting to a sandbox environment or production?

I believe that you can only connect to the Sandbox when starting through Xcode and if the application is “updated” from the App Store version, it will not start the Sandbox. At least, this is a tiny bit of Iood voodoo I witnessed ... This means that it can stop being true at any time, because the IAP setup is one sacrificial lamb from magic.

I am not 100% sure because I have not tested it yet, but I will let you know as soon as I do it.
