Ios 发布更新记录

我无法保存已保存的记录。recordToSave是从服务器下载的CKRecord。有可能更新吗

recordTosave.setValue("cat", forKey: "animal")

let publicData = CKContainer.defaultContainer().publicCloudDatabase

publicData.saveRecord(recordToSave, completionHandler:{(record: CKRecord?, error: NSError?) in
    if error == nil{  

    }else{
        print(error.debugDescription)
    }
})

无法插入cloudkit中已存在的记录。您可以使用CKModifyRecordsOperation修改记录。使用记录ID获取记录，然后通过修改操作进行更新

let recordIDToSave = CKRecordID(recordName: "recordID")
let publicData = CKContainer.defaultContainer().publicCloudDatabase

publicData.fetchRecordWithID(recordIDToSave) { (record, error) in

    if let recordToSave =  record {

        //Modify the record value here
        recordToSave.setObject("value", forKey: "key")

        let modifyRecords = CKModifyRecordsOperation(recordsToSave:[recordToSave], recordIDsToDelete: nil)
        modifyRecords.savePolicy = CKRecordSavePolicy.AllKeys
        modifyRecords.qualityOfService = NSQualityOfService.UserInitiated
        modifyRecords.modifyRecordsCompletionBlock = { savedRecords, deletedRecordIDs, error in
            if error == nil {
                print("Modified")
            }else {
                print(error)
            }
        }
        publicData.addOperation(modifyRecords)
    }else{
        print(error.debugDescription)
    }
}

我们需要更多的细节。printerror.debugDescription输出什么？如果这不起作用，请尝试打印错误。另外，您如何创建/检索要保存的记录？我们需要更多详细信息。printerror.debugDescription输出什么？如果这不起作用，请尝试打印错误。另外，您是如何创建/检索recordTosave的？不幸的是，它给了我一个错误：可选。我发现了这个错误，无论如何都要感谢Kiruthika。你的代码是正确的，解释得很好。感谢它，修改记录的好方法：不幸的是，它给了我一个错误：可选。我发现了这个错误，不管怎样，多亏了Kiruthika。你的代码是正确的，解释得很好。欣赏它，修改记录的好方法：
