Clear the applicationIconBadgeNumber but not clear the notice in the iOS notice board

Question

I want to clear the applicationIconBadgeNumber and keep the notification in the notification center for iOS 8 ~ 11. I have tried the code in the applicationDidBecomeActive:

UILocalNotification *notif = [[UILocalNotification alloc] init];
notif.applicationIconBadgeNumber = -1;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];

It works at the beginning but when I try more times, I can receive the UILocalNotification but cant change theapplicationIconBadgeNumber`.

Are there any other solutions or is my usage is wrong？

Instead of your code, use

if (@available(iOS 9, *)) {
    // iOS 9 (or newer) 
    [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
} else {
    // iOS 8
    [UIApplication sharedApplication].applicationIconBadgeNumber = -1;

}

to clear app icon badge. This will not clear the notification but counter will become zero on app icon.

You can write this code to clear count in

- (void)applicationWillEnterForeground:(UIApplication *)application

or

- (void)applicationDidBecomeActive:(UIApplication *)application
