I need to unzip / unzip compressed 7z files in ios , can anyone tell the libraries used for this, where these libraries are available for download. Is there any sample project for this, let me know
7-Zip Lzma SDK is a multilingual SDK for processing 7-zip files. Mo Dejong created an example demonstrating how to use the LZMA SDK to unpack 7-zip libraries on iOS devices. You can find an example on your website here .
iOS9 comes with LZMA support (encoder up to level 6, decoder of all levels). Of course, this will help if you just need compression - if you absolutely need to read the 7z archive / container format, you will need an external library.
