从Archive解压缩单个文件 [英] Unzipping a single file from Archive

问题描述

我正在尝试将现有的Android应用程序移植到iOS，
在Android应用程序中，我使用ZipInputStream从zip存档中提取单个文件并将其作为临时文件存储。

I'm trying to port an existing Android application to iOS, In the Android application i was using a ZipInputStream to extract a single file from the zip archive and store it in as a temporary file.

我如何从Zip档案中提取单个文件而不必提取整个档案（因为它非常大）？

How could i extract a single file from a Zip Archive without having to extract the whole archive (As it is very large)?

推荐答案

我刚刚找到答案，

我必须修改SSZipArchive以插入一个方法，从中提取单个文件ZIP存档（基于其名称）

I had to modify SSZipArchive to insert a method that will extract a single file from the ZIP archive (Based on its name)

您可以找到修改后的版本，如果有人发现这个有用，我可以清理它，添加代理，测试并建议拉入SSZipArchive。

You could find the modified version here, if someone finds this useful i might clean it up, add the delegate, the tests and propose for pull in SSZipArchive.

用法是直截了当：

NSString *zipEntityToExtract = @"example.aac";
NSString *destinationFilePath = ...; //(Includes filename)
NSString *zipPath = ...;
[SSZipArchive unzipEntityName:zipEntityToExtract fromFilePath:zipPath toDestination:filePath];
//File is now in destinationFilePath
