UICollectionView CocoaHeads SLC

For those of you who were able to attend my UICollectionView presentation at CocoaHeads SLC on the 2nd of July here is the sample code I promised. Those of you who weren't there, sorry you missed it. My slides aren't really worth publishing. If you are interested in some great presentations on UICollectionView, check out the 2012 WWDC session videos.

Here is the code. In addition to the two layouts that I demoed at the presentation, I added a parallex layout for your enjoyment.
