iphone – Cloudkit：CKNotificationInfo徽章值永不减少

我为cloudkit设置了订阅通知.这是我的代码：

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);
                       }

                       }];

工作得很好.问题是徽章,他们看起来像cloudKit没有重置徽章号码,并且即使我将徽章计数设置为零,也会不断增加.

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    application.applicationIconBadgeNumber = 0;
}

当应用程序收到新通知时,从0到5(每个新通知增加1,下一次将是6)

你们中的任何人都知道如何从cloudkit中跟踪正确的徽章数量(在Objective-C中)

解决方法

这是 CloudKit won’t reset my badge count to 0的副本

答案是：
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)
}
