ios - 我想将 .plist 转换为 sqlite

Question

我正在使用 plist 将数十个数据解析为 tableview。它工作得很好。然而，它是不 protected 。如果有人打开 .ipa 文件的内容，就可以轻松访问该 plist 文件。我想保护我的数据。有没有办法保护 .plist 文件？据我所知，Sqlite 通过将值更改为复杂的键来保护数据。然而，如果我要在我的应用程序中使用 sqlite，我必须更改将数据解析为字符串的方式。我对 SQLite 一无所知。

从哪里开始？你有什么建议？有没有更简单、更好的方法来保护 iOS 应用程序中的数据？

提前致谢。

如果您只想加密您的 plist 文件，请查看 at this SO question .

如果你真的想要sqlite，那么不要直接处理sqlite，看看CoreData . Core data 是一个 Apple 框架，它使得使用 NSObject 和关系来存储和获取数据变得非常容易。如果需要的话，核心数据可以使用sqlite来存储。学习曲线相当陡峭，但值得学习，因为它是一个非常有用的框架，需要掌握。

请记住，sqlite 数据库仅存储在默认情况下任何人都可以读取的文件中。因此您需要付出更多的努力来加密它。
