如何更改与iOS 7照片应用类似的选项卡

Question

I want to change the tab bar when you enable multiple selection to a UICollectionView or any other similar view like in photos App. Check the image below.

This is not a tab bar but a UIToolbar. You can add two toolbars in storyboard. On select button press just fade in the second toolbar(with add button).
