ios - Reset CKNotificationInfo badge value only for the current device -

-

i'm testing 3 idevices. device 1 fires cksubscription change notification.

device 2 , 3 receives notification , badge number increases 1.

i coded reset badge number 0 everytime app comes foreground below.(in applicationdidbecomeactive:)

ckmodifybadgeoperation *badgeresetoperation = [[ckmodifybadgeoperation alloc] initwithbadgevalue:0]; [badgeresetoperation setmodifybadgecompletionblock:^(nserror * operationerror) {     if (!operationerror) {         [uiapplication sharedapplication].applicationiconbadgenumber = 0;     } }]; [[ckcontainer defaultcontainer] addoperation:badgeresetoperation];

if user taps app on device 2, above code executed. works well. badge number reset 0. issue badge number on device 3 become 0 simultaneously, though didn't tap app on device 3.

i hope device 3 remains increased badge number since user didn't tap it.

api reference says 'this operation object can update badge current device or of user’s devices.'

https://developer.apple.com/reference/cloudkit/ckmodifybadgeoperation?language=objc

i believe means there's way reset single device want.

please guide me how accomplish it.

if 3 devices logged in same icloud id share same badge count. badges stored onto user's icloud account. why same across every device logged account.

log other devices on different icloud accounts , run test again. should work.

also, when saving subscriptions make sure saving same multiple times otherwise multiple badges same notification. check existence of subscription before saving again.
