SSZipArchive is a simple utility class for zipping and unzipping files. Features:

• Unzipping zip files
• Unzipping password protected zip files
• Creating zip files
• Appending to zip files
• Zipping files
• Zipping NSData with a filename
• Works in ARC and non-ARC projects

1. Add SSZipArchive.h, SSZipArchive.m, and minizip to your project.
2. Add the libz library to your target

You don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.

// Unzipping
NSString *zipPath = @"path_to_your_zip_file";
NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];

// Zipping
NSString *zippedPath = @"path_where_you_want_the_file_created";
NSArray *inputPaths = [NSArray arrayWithObjects:
                       [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
                       [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
                       nil];
[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];

Thanks aish for creating ZipArchive which SSZipArchive is based on, Johnnie Walker (@randomsequence) for implementing creation support, and John Engelhart (@johnezang) for all his amazing help along the way.
