iPhone文档目录最大尺寸 [英] iPhone Documents directory maximun size

问题描述

我只是想知道由于新的个人项目是我的应用程序的文档目录的限制（以MB或GB）。我只想保存很多照片，所以，文档目录对于归档下载的照片是一个限制？将节省300MB的照片在3G上产生减速吗？
如果没有限制，我认为限制是8 16 32 GB的iPhone，有没有办法知道可用空间？

解决方案

根据discussion.apple.com：限制为2 GB。

文件目录中的文件永久保留在应用程序删除之前。

I'm just wondering due to new personal project which is the limit (in MB or GB) of documents directory of my app. I just wanna save a lot of photos, so, has documents directory a limit for archiving downloaded photos? Will saving 300MB of photos produce slow downs on 3G? If there is no limit, I think that limit shoud be the 8 16 32 GB of the iPhone, are there any method to know the free space?

解决方案

According to a discussions.apple.com: There is a limit of 2 GB.

Files in the document directory stay there permanently until the app is removed.
