iOS 9: How to detect when user said 'Don't Allow' to the push notification request? [duplicate]

Answer 1

In your app delegate use this method

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings

then you can know if the user gave notification permissions by using

[[UIApplication sharedApplication] isRegisteredForRemoteNotifications]

or use the notificationSettings you receive.
