plist を使用して、数十のデータをテーブルビューに解析しています。それはかなりうまくいきます。とはいえ、無防備です。誰かが .ipa ファイルの内容を開くと、その plist ファイルに簡単にアクセスできます。データを保護したい。.plist ファイルを保護する方法はありますか? 私の知る限り、Sqlite は値を複雑なキーに変換することでデータを保護します。それでも、アプリに sqlite を使用する場合は、データを文字列に解析する方法を変更する必要があります。私はSQLiteについて何も知りません。
どこから始めれば？何を指示してるんですか？iOS アプリでデータを保護するためのより簡単で優れた方法はありますか?
前もって感謝します。
私のplistの例:
