如何删除CKRecord

Question

如何以编程方式在客户端从数据库中删除CKRecord。

for record in records {
    if recordNumber < 13 {
        let moodRecord:CKRecord = record as! CKRecord
        self.moodArray.append(moodRecord.objectForKey("Color") as! String)
    }
    else if recordNumber > 13 {
        // DELETE RECORD HERE
        record.delete(CKRecord)
        recordNumber--
    }
    recordNumber++
}

Answer 1

CloudKit中的记录不是这样删除的。下面是我如何删除应用程序中的记录：

let operation = CKModifyRecordsOperation(recordsToSave: nil, recordIDsToDelete: [record.recordID])
operation.savePolicy = .AllKeys
operation.modifyRecordsCompletionBlock = { added, deleted, error in
    if error != nil {
        println(error) // print error if any
    } else {
        // no errors, all set!
    }
}
CKContainer.defaultContainer().publicCloudDatabase.addOperation(operation)

Answer 2

您可以使用

删除(具有withRecordID:completionHandler：)

苹果文档

objc版本：

[aDatabase deleteRecordWithID:rec.recordID completionHandler:^(CKRecordID * _Nullable recordID, NSError * _Nullable error) {
    ;
 }];

Answer 3

let database = CKContainer.default().publicCloudDatabase // or privateCloudDatabase

let recordID = someRecord.recordID
    
database.delete(withRecordID: recordID) { (ckRecordID, error) in

    if let error = error {
        print(error.localizedDescription)
        return
    }
            
    guard let id = ckRecordID else {
        return
    }

    print(id)
}
