I am developing an app for iOS 8 and utilizing interactive notifications. For that one has to register notification settings with categories. Problem is I have to schedule local notification at different point of my app based on user inputs. So the question is if call this code
UIUserNotificationSettings *mySettings =
[UIUserNotificationSettings settingsForTypes:types categories:[NSSet setWithObject:myCategary]];
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
multiple times with different "myCategories" will it overwrite my existing categories or add to previous registered for local notifications?
It will overwrite the old settings as UIUserNotificationSettings is singleton. Find more explanation here:
