推荐答案

使用类似 ASIHTTP 从网络检索文件。这可以处理gzip，这可能是来自网络的数据被压缩。

Use something like ASIHTTP to retrieve the file off the network. That can handle gzip which is likely what the data coming off the network is compressed with.

如果您希望自行滚动，请查看此 zlib category 对NSData：在我以前工作得很好，可能会做你需要的。

If you'd prefer to roll your own, take a look at this zlib category on NSData: Has worked well for me in the past and likely does what you'll need.

您还需要将-lz添加到其他链接器标志构建设置

You'll also need to add -lz to the "other linker flags" build setting
