I've a home maid solution for you: https://github.com/mhausherr/Light-Untar-for-iOS

It's lighter than lib archive and may work for your use.

The best library I've found is libarchive. It is well-designed, well-documented, and fast.

I just created a repository on GitHub that has the tools to build libarchive and libbz2 as static libraries for iOS 4.2+. (It should be possible to use it to target 3.x, too.)

In other related questions on Stack Overflow, people have pointed out that libarchive is included in the SDK. This is not quite true. The binary libarchive.2.dylib is included, but the headers are not. The same applies to libbz2 (but, oddly, not to libz.) This means that libarchive is considered a private API -- in other words, you can't use it if you intend to ship on the App Store. Hence my repository.

Have you looked at libtar?
