1. About the libdmtx Cocoa Wrapper
This is a general Cocoa wrapper that includes CocoaTouch, so it can be used for iPhone/iPod Touch and general OS X development. It was written by Stefan Hafeneger, who donated the code and made it available under the LGPLv2.
This code provides a Cocoa class called SHDataMatrixReader.m, which is a singleton with a wrapper function for decoding and an image convert method (so there is no need for libpng). Notably, it uses the official iPhone SDK so jailbreak is not required.
