Notifications with MKStoreKit

Question

I use MKStoreKit for automatic renewable subscriptions and everything works fine, but I don't know what these notifications do. ( kSubscriptionsPurchasedNotification and kSubscriptionsInvalidNotification ).

When I call them in the ViewDidLoad or didFinishLaunchingWithOptions , their respective methods are called, but if([MKStoreManager isFeaturePurchased:@"myFeature"]) always returns false and enters the else statement. So why is this happening and what is the use of using them?

Secondly, as I said, I use automatic renewable subscriptions, when the subscription has expired, the subscription does not renew automatically, the user must click again to enter my application and subscribe manually.

If you work with subscriptions, you should use:

 [[MKStoreManager sharedManager] isSubscriptionActive:@"myFeature"]; 

not: [MKStoreManager isFeaturePurchased: @ "myFeature"]

 isFeaturePurchased: 

used to verify purchases in the Consumable app.
