Help with an iPad iBookstore-like Interface

I am building an iPad application that needs to list books in a manner similar to 开发者_运维技巧the way Apple does it in their iBookstore application and how Marvel does it in their iPad application. I'm not talking about the main featured rotating images but rather the book listing below that.

My question is looking at the book list, how are they being displayed? Is a series of sub-classed UIViews or a custom UITableViewCell? Or is it something else altogether different?

Thank you in advance for any help.

AQGridView. (That's not what iBooks is using, but it achieves the same effect)
