swift - Swift：CloudKit 订阅 firesOnRecordCreation 未按预期调用

问题描述

这是我的订阅方法注册

public func RegisterForSubscription(completion: @escaping (Result<CKSubscription, Error>) -> Swift.Void) {
    let subscription = CKQuerySubscription(recordType: Film.RecordType, predicate: NSPredicate(value: true), options: [.firesOnRecordCreation, .firesOnRecordDeletion, .firesOnRecordUpdate])

    let notificationInfo = CKSubscription.NotificationInfo()
    notificationInfo.shouldSendContentAvailable = true
    subscription.notificationInfo = notificationInfo

    database.save(subscription) { savedSubscription, error in
        if let error = error {
            print("Subscription error: \(error.localizedDescription)")
            completion(.failure(error))
            return
        }

        if let savedSubscription = savedSubscription {
            completion(.success(savedSubscription))
            return
        }
    }        
}

现在我所关心的.firesOnRecordCreation只是为了调试目的，我添加了所有三个选项。

当我尝试添加（保存）新记录时，它成功地将它们添加到 CloudKit。这是方法

public func save(film: Film, completion: @escaping (Result<CKRecord, Error>) -> Swift.Void) {
    let filmRecord = film.toRecord()
    
    let operation = CKModifyRecordsOperation(recordsToSave: [filmRecord], recordIDsToDelete: nil)
    operation.qualityOfService = .userInitiated
    operation.completionBlock = {
        completion(.success(filmRecord))
    }
    
    database.add(operation)
}

和我的.toRecord()方法：

public func toRecord() -> CKRecord {
    let record = self.record ?? CKRecord(recordType: Self.RecordType)
    record[RecordKeys.id.rawValue] = id
    record[RecordKeys.title.rawValue] = title
    record[RecordKeys.filmDescription.rawValue] = filmDescription
    record[RecordKeys.image.rawValue] = image
    record[RecordKeys.director.rawValue] = director
    record[RecordKeys.producer.rawValue] = producer
    record[RecordKeys.releaseDate.rawValue] = releaseDate
    record[RecordKeys.rtScore.rawValue] = rtScore
    record[RecordKeys.imdbLink.rawValue] = imdbLink
    record[RecordKeys.imdbScore.rawValue] = imdbScore
    
    return record
}

一切正常。但是，我想注册订阅（静默通知）以在用户添加新记录（电影）时检测实时更改。

问题是，每当我通过该方法添加（调用保存方法）时，它都不会触发该.firesOnRecordCreation选项。但是，其他两个工作。我通过 CloudKit 仪表板更新了其中一个属性并删除了它们，它被称为（在 appDelegate 上didReceiveRemoteNotification）

我究竟做错了什么？当用户从方法（不是 VIA 仪表板）添加新电影时，它应该触发它，但在这种情况下不是。

编辑：

通过仪表板添加触发订阅。但不是在使用该方法时。
