我正在尝试设置一个 Cloudkit 订阅，每次创建特定记录类型的新记录时都会向我发送通知。我用来设置订阅的代码如下。

它正在一台设备上运行。如果我在另一台设备上创建新记录，它会收到通知。

但相同的代码在另一台设备上运行时会返回 Type 11 错误。这个相同的设备能够创建这种类型的记录并存储它。

我完全被难住了。任何关于正在发生的事情以及如何解决它的指针将不胜感激！

 NSPredicate *predicate = [NSPredicate predicateWithFormat:@"TRUEPREDICATE"];
    CKSubscription *artisSubscription = [[CKSubscription alloc]
                                         initWithRecordType:@"DummyRecordType"
                                         predicate:predicate
                                         options:CKSubscriptionOptionsFiresOnRecordCreation];

    CKNotificationInfo *notificationInfo = [CKNotificationInfo new];
    notificationInfo.alertLocalizationKey = @"how many dummies will I get.";
    notificationInfo.shouldBadge = YES;

    artisSubscription.notificationInfo = notificationInfo;

[self.publicDatabase saveSubscription:artisSubscription
               completionHandler:^(CKSubscription *subscription, NSError *error) {
                   if (error)
                   {
                       NSLog(@"error %@ while saving subscription %@",error,artisSubscription) ;
                   }
                   else
                   {
                       NSLog(@"Successfully created subscription") ;
                   }
               }];

此 NSLog 显示设备能够创建 DummyRecordType 类型的记录

此 NSLog 显示设备无法为相同的记录类型 DummyRecordType 创建订阅
