ios - 访问 ios 应用程序文档和其他文件

Question

我怀疑是否有人可以访问 iphone 应用程序的文件和文档目录。需要检查任何人在获得设备后是否可以访问这些文件。我的应用程序中有一个 sqlite 文件，其数据是敏感的，我不希望其他用户破解或访问它。请告诉我如何访问任何应用程序数据库。

Answer 1

这取决于用户，基本上，如果用户设置了密码，它将加密设备上的所有数据。如果用户没有设置密码，那么数据将以未加密的方式存在。根据经验，您必须假设如果信息存在于设备上，则该信息可能存在风险。

苹果是这样说的:

Data protection is available for devices that offer hardware encryption, including iPhone 3GS and later, all iPad models, and iPod touch (3rd generation and later). Data protection enhances the built-in hardware encryption by protecting the hardware encryption keys with your passcode. This provides an additional layer of protection for your email messages attachments, and third-party applications.]1

还有:

On devices running iOS 8, your personal data such as photos, messages (including attachments), email, contacts, call history, iTunes content, notes, and reminders is placed under the protection of your passcode.
