CKSubscription型CKSubscriptionOptionsFiresOnRecordUpdate不起作用

Question

我设置一个CKSubscription用下面的代码：

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:当添加一个新的记录我得到通知，但在现有的记录被更新，我从来没有得到通知。

我试过从CloudKit仪表板和从另一台设备登录到同一个帐户更新记录。

我测试在iOS 9测试版5.

它是一个已知的bug是更新通知不工作。

[CKFetchNotificationChangesOperation sometimes does not return UPDATE, DELETE notifications [CloudKit push notifications on record update stopped working [https://forums.developer.apple.com/thread/7288][3]
