TKCoverflowView Class Reference

Inherits from	UIScrollView
Conforms to	UIScrollViewDelegate
Declared in	TKCoverflowView.h

Overview

TKCoverflowView imitates the coverflow you’d find in the iPod/Music app on the iPhone OS. Coverflow displays TKCoverflowCoverView objects. This view functions similar to the UITableView where covers that are off screen aren’t loaded until need. Thus, similar to the tableview, you can dequeue a cover view and hand it back to Coverflow View using the data source.
