是的，它需要一个接一个地完成。你需要从旧区域中获取所有的，然后为新的自定义区域创建一个新的，就像这样：

func newRecord(from record: CKRecord, newZone: CKRecordZone) -> CKRecord {

    let recordID = CKRecordID(recordName: record.recordID.recordName, zoneID: newZone.zoneID)
    let newRecord = CKRecord(recordType: "Goal", recordID: recordID)

    newRecord["startDate"] = record["startDate"]
    newRecord["endDate"] = record["endDate"]
    newRecord["hours"] = record["hours"]

    return newRecord
}

字符串
并保存到CKDatabase。
