"解压"在iPhone上的文件 [英] "Untar" file on iPhone

问题描述

我正在编写一个从Web服务器下载tar-gzip文件的iPhone应用程序，然后需要取消归档此文件，以便将其复制到应用程序的Documents文件夹中。

I'm writing an iPhone app which downloads a tar-gzipped file from a Webserver, then needs to unarchive this file so that it can be copied into the app's Documents folder.

我正在使用tar / gzip，因为我想在一个HTTP请求中下载一大堆小文件，以使一切变得美观和快速。

I'm using tar/gzip because I want to download a whole bunch of small files in one HTTP request, to make everything nice and fast.

I已经调查了像 http://www.feep.net/libtar/ 这样的解决方案，但作为C / Objective-C newb，我无法让他们中的任何一个为iPhone平台编译。

I've investigated solutions like http://www.feep.net/libtar/, but as a C/Objective-C newb, I can't get any of them to compile for the iPhone platform.

（我觉得我应该能够进行系统调用到tar -zxvf myfile.tar.gz，但它看起来并不那么容易！）

(I felt like I should just be able to do a system call to "tar -zxvf myfile.tar.gz", but it would appear it's not that easy!)

所以有一种简单的方法可以解压缩文件在iPhone上？或者我是否认为这是错误的，有更好的方法吗？

So is there a simple way to just un-tar a file on the iPhone? Or am I going about this all wrong, and is there a better way to do this?

提前致谢！
