2.3 - Apps that do not perform as advertised by the developer will be rejected
2.3 Details
Your app has the UIFileSharingEnabled key set to true in the info.plist, but the Documents folder includes files and folders not intended for file sharing.

Next Steps
Please move all files that that are not intended for user access via the file sharing feature to another part of your application's sandbox. When file sharing is enabled, the entire Documents folder is used for file sharing.

UIFileSharingEnabled设为true,你开启了文件共享, 却不让用户尽情的使用,你可以丢几张图片在共享到itunes的文档里,但不能没有

解决方案

1. 修改重要文件(用户看不懂的文件)的存储路径 .
2. 关闭UIFileSharingEnabled
