Features:\n\n* Unzipping zip files\n* Unzipping password protected zip files\n* Creating zip files\n* Appending to zip files\n* Zipping files\n* Zipping NSData with a filename\n* Works in ARC and non-ARC projects\n\n## Adding to your project\n\n1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.\n2. Add the `libz` library to your target\n\nYou don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.\n\n## Usage\n\n``` objective-c\n// Unzipping\nNSString *zipPath = @\"path_to_your_zip_file\";\nNSString *destinationPath = @\"path_to_the_folder_where_you_want_it_unzipped\";\n[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];\n\n// Zipping\nNSString *zippedPath = @\"path_where_you_want_the_file_created\";\nNSArray *inputPaths = [NSArray arrayWithObjects:\n [[NSBundle mainBundle] pathForResource:@\"photo1\" ofType:@\"jpg\"],\n [[NSBundle mainBundle] pathForResource:@\"photo2\" ofType:@\"jpg\"]\n nil];\n[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];\n```\n\n## License\n\nSSZipArchive is licensed under the [MIT license](https://github.com/samsoffes/ssziparchive/raw/master/LICENSE). A slightly modified version of [Minizip](http://www.winimage.com/zLibDll/minizip.html) 1.1 is also included and is licensed under the [Zlib license](http://www.zlib.net/zlib_license.html).\n\n## Thanks\n\nThanks [aish](http://code.google.com/p/ziparchive) for creating [ZipArchive](http://code.google.com/p/ziparchive) which SSZipArchive is based on, Johnnie Walker ([@randomsequence](https://github.com/randomsequence)) for implementing creation support, and John Engelhart ([@johnezang](https://github.com/johnezang)) for all his amazing help along the way.\n" }, { "path": "SSZipArchive.h", "content": "//\n// SSZipArchive.h\n// SSZipArchive\n//\n// Created by Sam Soffes on 7/21/10.\n// Copyright (c) Sam Soffes 2010-2011.

Changes\n Oct-2009 - Mathias Svensson - Remove old C style function prototypes\n Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives\n Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.\n Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data\n It is used when recreting zip archive with RAW when deleting items from a zip.\n ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.\n Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)\n Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer\n\n*/\n\n\n#include \n#include \n#include
