I don't know much about this, I had seen a comment in discussions.apple.com like: There is a limit of 2 GB. 我不知道很多关于这一点，我已经看到在discussions.apple.com评论一样： 有2 GB的限制。

Files in the document directory stay there permanently until the app is removed. 文档目录中的文件会永久保留在该目录中，直到删除该应用程序为止。

the fact is: 2Gb is the app size limit, and the app's directory can more than 2Gb; 事实是：2Gb是应用程序的大小限制，并且应用程序的目录可以超过2Gb； I found it from apple doc is here , search keyword "2G" 我从苹果文档中找到它，搜索关键字“ 2G”

I don't know if apple did some change, I use an app named PPTV, it can store videos from server, and more than 2Gb; 我不知道苹果是否做了一些改变，我使用了一个名为PPTV的应用程序，它可以存储来自服务器的视频，并且可以存储超过2Gb的视频； what happens? 怎么了？

You should use Cache Directory if you want to cache anything without user's action or your app will get rejected if you dont follow the instructions: 如果要缓存任何内容而无需用户采取任何措施，则应使用“缓存目录”，否则，如果不遵循以下说明，您的应用将被拒绝：
