Introducing UICollectionView0:56 with Sam Soffes

IOS six called UICollectionView, and it's amazing.
You can show items every which way.
Something as simple as a grid, or even as complex as counter flow.
That's actually CollectionView's biggest strength, is how flexible its layouts are.

You have a data source, delegate,section, cells, headers, footers.
Collection view does a lot of things similar to UITableView.
So this may be very familiar.
If you're not familiar with UITableView though, that's okay.
We'll go through it together.
You get a CollectionView cells to show on the screen.
You can then provide a layout to customize how it all gets displayed.
So you can make it look like this, this, or even this.
Let's dive in.
