CloudKit不会将我的徽章计数重置为0

Question

我已经尝试了很多东西,似乎无法重置来自cloudKit的通知的徽章数量.有没有其他人遇到过这个问题.这是我尝试过的:

1)将徽章计数本地设置为0

  application.applicationIconBadgeNumber = 0; (temporarily removes the badge count).

没运气...

2)调用服务器以清除徽章计数

 CKModifyBadgeOperation *oper = [[CKModifyBadgeOperation alloc] initWithBadgeValue:0];
  [oper start];

没运气...

3)拉入所有通知更改并将其全部标记为已读

NSMutableArray *array = [NSMutableArray array];
CKFetchNotificationChangesOperation *operation = [[CKFetchNotificationChangesOperation alloc] initWithPreviousServerChangeToken:nil];
operation.notificationChangedBlock = ^(CKNotification *notification) {
    [array addObject:notification.notificationID];
};
operation.completionBlock = ^{
        CKMarkNotificationsReadOperation *op = [[CKMarkNotificationsReadOperation alloc] initWithNotificationIDsToMarkRead:array];
        [op start];
};
[operation start];

再一次没有运气......

任何建议将不胜感激!谢谢,克里斯

处理完通知后,您需要执行CKModifyBadgeOperation .

这是我的Swift函数,我将所有通知标记为已读时调用.我将操作添加到defaultContainer而不是仅仅启动它 - 我想知道这有什么不同.

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)
}
