There is nothing in iOS 6 that does zip/unzip. See one of the many existing threads on SO that cover this topic (ZipArchive, Objective-Zip, etc.).

zipzap is a new comer. Features:

  • Easy-to-use interface: The public API offers just three classes! Yet you can look through zip files using familiar NSArray collections 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.
