问题描述

我想扩展我的iPhone应用程序，应用程序将一个zip文件下载到
a子目录，然后提取它，然后加载zip内的图像。

I want to extend my iPhone app that the app downloads a zip file into a sub directory then extracts it and then load images which were inside the zip.

有关如何在运行时解压缩和访问图像的任何想法？对于某些想法真的很开心。

Any ideas how to unzip in run-time and the access the images? Would be really happy for some idea.

问候，

推荐答案

我过去曾成功使用 ZipArchive 。

它非常轻巧，使用简单，支持密码保护，ZIP内的多个文件，以及压缩和放大解压缩。

It's pretty ligthweight and simple to use, supports password protection, multiple files inside a ZIP, as well as compress & decompress.

基本用法是：

NSString *filepath = [[NSBundle mainBundle] pathForResource:@"ZipFileName" ofType:@"zip"];
ZipArchive *zipArchive = [[ZipArchive alloc] init];
[zipArchive UnzipOpenFile:filepath Password:@"xxxxxx"];
[zipArchive UnzipFileTo:{pathToDirectory} overWrite:YES];
[zipArchive UnzipCloseFile];
[zipArchive release];
