CloudKit 不会将我的徽章计数重置为 0 [英] CloudKit won't reset my badge count to 0

问题描述

我尝试了很多方法，但似乎无法从来自 cloudKit 的通知中重置徽章计数.有没有其他人遇到过这个问题.这是我尝试过的:

I've tried a number of things and can't seem to reset the badge count from notifications comings from cloudKit. Has anyone else ran into this problem. Here is what I've tried:

1) 在本地设置徽章计数为 0

1) Set the badge count locally to 0

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

运气不好...

2) 调用服务器清除徽章计数

2) Call the server to clear the badge count

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

运气不好...

3) 拉入所有通知更改并将它们标记为已读

3) Pull in all notification changes and mark them all read

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];

再次没有运气...

任何建议将不胜感激！谢谢，克里斯

Any suggestions would be greatly appreciated! Thanks, Chris

推荐答案

您需要在处理通知后执行 CKModifyBadgeOperation.

You need to do a CKModifyBadgeOperation after processing your notifications.

这是我在将所有通知标记为已读后调用的 Swift 函数.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.

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)
}
