ios - CloudKit 订阅有时不起作用

Question

如果我尝试使用此代码订阅 CloudKit:

    NSPredicate *truePredicate = [NSPredicate predicateWithValue:YES];
    CKSubscription *itemSubscription = [[CKSubscription alloc] initWithRecordType:RecordType
                                                                        predicate:truePredicate
                                                                          options:CKSubscriptionOptionsFiresOnRecordCreation | CKSubscriptionOptionsFiresOnRecordUpdate | CKSubscriptionOptionsFiresOnRecordDeletion];


    CKNotificationInfo *notification = [[CKNotificationInfo alloc] init];
    notification.alertBody = @"Item Added/Updated/Deleted!";
    itemSubscription.notificationInfo = notification;

    [self.publicDatabase saveSubscription:itemSubscription completionHandler:^(CKSubscription *subscription, NSError *error) {
        if (error) {
            // In your app, handle this error appropriately.
            NSLog(@"An error occured in %@: %@", NSStringFromSelector(_cmd), error);
        } else {

            NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
            [defaults setObject:subscription.subscriptionID forKey:kSubscriptionID];
            [defaults synchronize];
        }
    }];

我有时会遇到这个错误:

CKError 0x17558460:“服务器拒绝请求”(15/2000)；服务器消息=“内部服务器错误”； uuid = B89DE7A4-9D22-42BC-9CD4-4330F3FE04EF;容器 ID = "iCloud.com.app.testApp"

或

CKError 0x14fb3510:“服务不可用”(6/2022)；服务器消息 = “无法安装架构，CAS 失败”； uuid = F562D1AD-B40E-4842-A5EA-2A5F800C18F2;容器 ID = "iCloud.com.app.testApp"

有人知道怎么解决吗？我可以用我的代码做些什么吗？这是苹果的问题，我什么也做不了？谢谢。

我最近遇到了类似的错误，并且能够通过在项目的功能中切换 CloudKit 来解决它。一旦我重置了 CloudKit 权限，一切似乎都运行良好。
