Just over a year ago I mentioned a number of open source libraries for handling Zip, RAR and 7-Zip archives on the iOS platform.

A couple of people have e-mailed me about some issues they had when handling zips, and today I came across a new library that offers a very simple interface with zip/unzip and rezip classes.

Here are the features mentioned in the readme:

– Easy-to-use interface: The public API offers just three classes! Yet you can look through zip files using familiar NSArraycollections and properties. And you can zip, unzip and rezip zip files through familiar NSData, NSStream and Image I/O classes.

– Efficient implementation: We’ve optimized zip file reading and writing to reduce virtual memory pressure and disk file thrashing. Depending on how your compound document is organized, updating a single entry can be faster than writing the same data to a separate file.

– File format compatibility: Since zipzap closely follows the zip file format specification, it is works with most Mac, Linux and Windows zip tools.

You can find the library known as ZipZap by Glen Low on Github here.

A great looking for an easy to use Zip compression library.
