SKProductsRequest delegate methods are never called

Question

This worked for me, but now no longer works, and I can’t understand why. I have an app to buy apps in the app. I have confirmed that I have the correct set of product identifiers that matches the corresponding in-app purchase items in itunesconnect. The call goes to the Apple view [productRequest start] , but I never get a response, despite the delegate delegating it myself. What am I missing?

 NSLog(@"productIdentifiersSet: %@", productIdentifiersSet); if ([productIdentifiersSet count]) { SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiersSet]; [productRequest setDelegate:self]; [productRequest start]; } 

.........

 - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { <never called> } - (void)requestDidFinish:(SKRequest *)request { <never called> } - (void)request:(SKRequest *)request didFailWithError:(NSError *)error { <never called> } 

Answer 1

The same thing happened to me today. In the morning, my code worked, in the afternoon it did not work for 3-4 hours. I spent all my time and tried a lot of things. But a little earlier, he began to work himself. I didn’t change anything.

I suppose we cannot trust Apple's servers about this.

Here is a good checklist that can solve these problems:

• Go to Settings \ iTunes and App Stores, log out of any account and try again to make sure you are using a Sandbox account.
• Check this link if it does not respond, the iTunes sandbox may not be available.
• Have you enabled in-app purchase for your app id?
• Do your .plist Bundle ID projects match your application ID?
• Do you use the full product identifier when creating SKProductRequest?
• Have you waited several hours since adding your product to iTunes Connect?
• Are your bank details active in iTunes Connect?
• Did you try to uninstall the application from the device and reinstall?
• Once you have created your products for the purchase of applications, do not forget to add them to your game application on the page of your application in ituns connect.
