iOS - Check for push notification support in the app

Question

I added Push notifications to my application. And my application works based on push notifications. When the app runs for the first time, it is showing alert whether user wants to receive push notifications or not. Is it possible to make it mandatory to accept push notifications? Or if this is not possible, can we check whether push notifications are set for this app or not and terminate the application with alert?

Answer 1

You can only check whether user have selected to receive push-notifications:

UIRemoteNotificationType status = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (status == UIRemoteNotificationTypeNone)
{
    NSLog(@"User doesn't want to receive push-notifications");
}

Answer 2

//It's better to use the followiing instead

BOOL status = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications]; if (!status) { NSLog(@"User doesn't want to receive push-notifications"); }

Answer 3

If your app target >= iOS 8.0 you can use:

UIApplication.sharedApplication().isRegisteredForRemoteNotifications()

as enabledRemoteNotificationTypes is deprecated.
