Answer 1

FrenchKiss Dev给出的答案不正确。用户仍然可以在 iTunes 中看到“.data”目录，并将其及其内的所有文件保存在本地。

相反，将私有(private)文档存储在库/首选项

According to Apple :

In addition to the directories documented previously, the entire /Library directory has always been preserved during updates and backups, except for /Library/Caches. Because of this, applications can create their own directories in /Library/ and those directories will be preserved in backups and across updates. To minimize the risk of name collisions, we recommend that you name this directory carefully. For example, a directory named Private Documents would be a good choice. You should store any files you don't want to share to Library/Preferences.
