This library is a fork of SSZipLibrary

Due to lack of mainteinance of the SSZipLibrary repository, we decided to create this fork. This fork will be maintained independent from SSZipLibrary, so we don't have plans to pull changes merged in SSZipLibrary.

Feel free to contribute to PDKTZipLibrary


PDKTZipArchive is a simple utility class for zipping and unzipping files.

You can do the following:

  • Unzip zip files;
  • Unzip password protected zip files;
  • Create new zip files;
  • Append to existing zip files;
  • Zip files;
  • Zip-up NSData instances. (with a filename)

How to add PDKTZipArchive to your project

  1. Add the PDKTZipArchive and minizip folders to your project.
  2. Add the libz library to your target

PDKTZipArchive requires ARC.


// Unzipping
NSString *zipPath = @"path_to_your_zip_file";
NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
[PDKTZipArchive 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"]
[PDKTZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];

// Zipping directory
[PDKTZipArchive createZipFileAtPath:zippedPath withContentsOfDirectory:inputPath];
