Cloudkit: CKNotificationInfo badge value never decrease - iphone

Question

I set subscription notifications for cloudkit. Here is my code:
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"TRUEPREDICATE"];
CKSubscription *subscription = [[CKSubscription alloc]
initWithRecordType:recordType
predicate:predicate
options:CKSubscriptionOptionsFiresOnRecordCreation];
CKNotificationInfo *notificationInfo = [CKNotificationInfo new];
notificationInfo.alertLocalizationKey =#"New record in cloudKit";
notificationInfo.shouldBadge = YES;
notificationInfo.soundName = UILocalNotificationDefaultSoundName;
notificationInfo.shouldSendContentAvailable = YES;
subscription.notificationInfo = notificationInfo;
CKContainer *container = [CKContainer defaultContainer];
CKDatabase *publicDatabase = [container publicCloudDatabase];
[publicDatabase saveSubscription:subscription
completionHandler:^(CKSubscription *subscription, NSError *error) {
if (!error)
{
NSLog(#"no error");
}
else
{
NSLog(#"error%#", error);
}
}];
and works just fine. The problem is the badges, they seem like cloudKit doesn't reset the badge number and the keep increasing even when I set the badge count to zero.
- (void)applicationDidBecomeActive:(UIApplication *)application
{
application.applicationIconBadgeNumber = 0;
}
When the app received a new notification goes from 0 to 5 (and every new notification increase by 1, the next time would be 6)
Any of you knows how keep track of the right count of badges from cloudkit (in Objective-C )

This is a duplicate of CloudKit won't reset my badge count to 0
The answer there was:
You need to do a CKModifyBadgeOperation after processing your notifications.
Here is my Swift function which I call after marking all the notifications as read. I add the operation to the defaultContainer instead of just starting it - I wonder does that make any difference.
func resetBadgeCounter() {
let badgeResetOperation = CKModifyBadgeOperation(badgeValue: 0)
badgeResetOperation.modifyBadgeCompletionBlock = { (error) -> Void in
if error != nil {
println("Error resetting badge: \(error)")
}
else {
UIApplication.sharedApplication().applicationIconBadgeNumber = 0
}
}
CKContainer.defaultContainer().addOperation(badgeResetOperation)
}

This will help.
CKModifyBadgeOperation *badgeResetOperation = [[CKModifyBadgeOperation alloc] initWithBadgeValue:0];
[badgeResetOperation setModifyBadgeCompletionBlock:^(NSError * operationError) {
if (!operationError) {
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}
}];
[[CKContainer defaultContainer] addOperation:badgeResetOperation];
