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

Answer 1

Check by this method:-

[[UIApplication sharedApplication] isRegisteredForRemoteNotifications];

But if your app supports less than iOS 8 version then you have to do the checking like this:-

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types == UIRemoteNotificationTypeNone) 
{ 
  //notification is not enabled by user

}
