Xamarin iOS：无法从 icloud 中的私有数据库中获取记录

Question

想要将资产保存到私有数据库，但是...... ...我的输出显示每次启动 "creating file..."，那么我的代码哪里出了问题？ :( （uploading/saving 似乎有效，因为 "uploaded" 出现了）

    var recordID = new CKRecordID("diary");
    AppleHelper.PrivateDatabase.FetchRecord(recordID, (record, err) => {

    // Was there an error?
    if (err != null) {
        Console.WriteLine(err.ToString());
        Console.WriteLine("creating file...");

        var dbName = "diary.db";
        var dbPath = Path.Combine(documents.Path, dbName);
        AppDelegate.lib.Conn = new SQLite.SQLiteConnection (dbPath);
        AppDelegate.lib.Conn.CreateTable<LibChemotherapie.Diary> ();

        if (File.Exists (dbPath)) {

            var assetRecord = new CKRecord ("sqlite");
            var db = new CKAsset(NSUrl.CreateFileUrl(new string[] { dbPath }));
            assetRecord ["diary"] = db;

            AppleHelper.PrivateDatabase.SaveRecord (assetRecord, (record2, err2) => {

                if(err2 == null)
                    Console.WriteLine("uploaded");

            });

        }
    }
    else {

        Console.WriteLine("yeah exists");

    }
    });

谢谢，我解决了问题。我无法获取我存储的记录。问题是，我没有使用 RecordID 进行加载，而是用于保存。
