I integrated the Push Notification to the CloudKit so that every change in the iCloud will pop up a notification on my iPhone and the badge app icon number will add one correspondingly. However, when I used the code:
application.applicationIconBadgeNumber = 0
to reset that number in the applicationDidBecomeActive(_ application: UIApplication), I noticed that the badge app icon number truly disappeared but if another new notification came again, the number won't start from one again as supposed but just add one to the original total number before the reset. Therefore the number is getting bigger and bigger. I wonder how to solve this problem?
I find that I should not only set the application side like:
UIApplication.sharedApplication().applicationIconBadgeNumber = 0
but I should also set the iCloud side in CKContainer. Therefore, the complete code is like below:
let operation = CKModifyBadgeOperation(badgeValue: 0)
operation.modifyBadgeCompletionBlock = {(error) in
if let error = error{
print("\(error)")
return
}
application.applicationIconBadgeNumber = 0
}
CKContainer.default().add(operation)
