The major new widget that will have the biggest impact on app interfaces is the collection view. A collection view is like a table view on steroids. A table view is the scrolling column of cells commonly seen in any master–detail app where a list must be displayed; Settings, Mail, and Music are familiar examples. A collection view breaks the bonds of the single vertically scrolling column, so you can expect, in short order, to see horizontally scrollable rows of data, multicolumn tables, and grids of information.
I’m not really a fan of these horizontally scrolling views, though. They seem like a flashy but less functional version of the basic column view.
