问题
In my app I need to set badge onto the app icon and set numbers for this badge. The problem is that I need to register user notification settings like this:
if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil]];
}
in order to make it work on iOS8. If I run this code then on start system presents an alert to the user which says something like:ApplicationName would like to send you notifications. Notifications may include bla la bla. It's the standard one, I'm sure you've seen it many times. Just because I registered notification settings the system thinks my app is going to post some notifications. But it's not! I don't want to post notifications. All I wanna do is to set badge onto the icon and a number onto this badge. Is there any possibility to achieve this on iOS 8 without registering user notifications or registering but not showing that system alert? Any ideas, guys?

The documentation is explicit on that point, on iOS8 and later, you have to register for user notifications :
@property(nonatomic) NSInteger applicationIconBadgeNumber; // set to 0 to hide. default is 0. In iOS 8.0 and later, your application must register for user notifications using -[UIApplication registerUserNotificationSettings:] before being able to set the icon badge.
