在提交到应用商店之前添加了AddSkipBackupAttributeToItemAtPath(addSkipBackupAttributeToItemAtPath before commit to app store)

在将应用程序提交到App Store之前，我应该在项目中标记我的coreData文件"skip backUp Attribute"吗？ 如果我不想备份任何文件，我必须跳过哪些文件夹？ 感谢帮助。

Should I mark my coreData file "skip backUp Attribute" in my project before I commit my app to App Store? And if I don't want to backup any files,which folders I must to skip? Thanks for help.

iOS数据存储指南指出，只有用户使用您的应用创建的内容（例如文档，新文件，编辑等）才能由iCloud备份。

应用程序使用的临时文件只应存储在/ tmp目录中; 请记住在用户退出应用程序时删除存储在此位置的文件。

iOS - 将整个文档目录标记为不备份

The iOS Data Storage Guidelines indicate that only content that the user creates using your app, e.g., documents, new files, edits, etc., should be backed up by iCloud.

Temporary files used by your app should only be stored in the /tmp directory; please remember to delete the files stored in this location when the user exits the app.
