CKFetchNotificationChangesOperation有时不会返回UPDATE，DELETE通知 [英] CKFetchNotificationChangesOperation sometimes does not return UPDATE, DELETE notifications

问题描述

CKFetchNotificationChangesOperation 返回INSERT操作，但并不总是UPDATE和DELETE。 DELETE，UPDATE在我向App Store提交应用程序时最后工作，但现在不再了。为什么？我创建了以下订阅：

CKFetchNotificationChangesOperation returns INSERT operations, but UPDATE and DELETE, not always. DELETE, UPDATE worked last when I submitted app to App Store, but now not anymore. Why? I have created subscriptions like:

let s = CKSubscription(recordType: recordType, predicate: NSPredicate(value: true), options: .FiresOnRecordCreation | .FiresOnRecordUpdate | .FiresOnRecordDeletion)
s.notificationInfo = CKNotificationInfo()
subscriptionsToSave.append(s)

仪表板显示所有树触发器：

Dashboard shows all tree triggers:

我不使用任何 alertBody ，所以通知是这样的叫做无声通知，可原因吗？

I do not use any alertBody, so notification is a so called silent notification, can it be the cause?

在 CloudKit提示和技巧讲师说，订阅需要从开发人员门户打开应用程序ID的APS功能。我不认为我有，但我只想要提取通知，只有在这种情况下才推送。

In CloudKit Tips and Tricks lecturer says that subscription needs APS capability for app ID turned on from the developer portal. I don't think I have, but I just want fetch notifications, push only if this works.

背景功能？ - 同样

需要在app的信息plist中设置APS环境密钥。 - 我想我已经拥有它了。

Need to set up APS environment key in app's info plist. - I guess I have it.

推荐答案

我知道这个问题已经过时了，但对于那些Google搜索，请务必查看此内容关于通知不一致的全面帖子：

I know this question is old, but for those Googling, be sure to check out this thorough post on the inconsistency of notifications:

无声推送未在iOS 11上发送到应用程序

我发现了一个特别微妙的修复。

I found a particularly subtle fix that I mention here.
