类型为CKSubscriptionOptionsFiresOnRecordUpdate的CKSubscription不起作用 [英] CKSubscription of type CKSubscriptionOptionsFiresOnRecordUpdate doesn't work

问题描述

我使用以下代码设置了 CKSubscription ：

I setup a CKSubscription with the following code:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"TRUEPREDICATE"];
CKSubscription *subscription = [[CKSubscription alloc] initWithRecordType:@"RecordTypeName"
                                                                 predicate:predicate
                                                            subscriptionID:@"Subscription1"
                                                                   options:CKSubscriptionOptionsFiresOnRecordCreation | CKSubscriptionOptionsFiresOnRecordUpdate];

CKDatabase *privateDatabase = [[CKContainer defaultContainer] privateCloudDatabase];
 [privateDatabase saveSubscription:subscription completionHandler:^(CKSubscription * _Nullable subscription, NSError * _Nullable error) {
     if (error) {
         NSLog(@"Failed to subscribe.");
     }
 }];

在 application：didReceiveRemoteNotification：当添加新记录时，但是在更新现有记录时却从未收到通知。

In application:didReceiveRemoteNotification: I get notified when a new record is added, but I never get notified when an existing record is updated.

我尝试从CloudKit仪表板和其他已签名的设备更新记录

I've tried updating records from both the CloudKit dashboard and from another device signed into the same account.

我正在iOS 9 beta 5上进行测试。

I'm testing on iOS 9 beta 5.

推荐答案

它是一个已知的错误，无法更新通知。

Its a known bug that update notifications are not working.

[ CKFetchNotificationChangesOperation有时不返回UPDATE，DELETE通知
[有关记录更新的CloudKit推送通知已停止工作
