In my previous post I demonstrated how to use AutoLayout and make UIImageView resize to full screen when in landscape mode. While happy with the outcome - the solution was not exactly what I wanted in the 1.2 version of Gun Vault. I wanted to allow to user to view all images from the item details screen using a scrollable carousel-style UICollectionView. I still wanted to have the carousel resize to full screen when in landscape mode as well prepare for future iPad oriented optimizations. It turned out that making a UICollectionView behave the same way as a UIImageView is much more difficult so I hope this article saves you time if you are trying to accomplish something similar so let’s get going.
