Wrapper Helper Classes for ABAddressBook

I have been looking for ways to integrate Address Book - Contracts to my application. Although Address Book Programming Guide for iOS provides information, APIs and example codes, all those resources are far away from what I need.

Then I found this ABContactHelper project on github. The project contains several wrapper ObjC classes to wrap CF classes: ABContact for contact, ABGroup for group and ABContractHelper for CF functions. I like those helper classes. The only thing I found so far I don't like is the contactName property. It formats a name in western way, not localized. Instead, the compositeName is an alternative choice, which just uses iPhone's AddressBook C function to return a composite name.

Those helper ObjC classes provide a good overview of ABAddress Book framework.
