For my iPad Dev Camp Hackathon project I'm releasing
AQGridView, formerly known
KBGridView, written for the Kobo iPad application(iTunes link).
It was designed to fill the role of
NSCollectionView, with an API and internals
UITableView. Full details are found on its GitHub project page.
It's not necessarily 100% perfect yet (I've not written any test apps against the refactored/renamed code) but people here want to use it already, so up it goes.
