ALGReversedFlowLayout is a subclass of UICollectionViewFlowLayout which lays out its items bottom-to-top instead of top-to-bottom.
To run the example project, just do pod try https://github.com/algal/ALGReversedFlowLayout.git. Run the example project in the simulator with a 4" device. Play with the switches in the example project to compare it to the normal flow layout, and to see the effect of the two configurable properties expandsContentSizeToBounds and minimumContentSizeHeight.
To use it in your app, just programatically instatiate this class exactly as you would UICollectionViewFlowLayout. Or if you are creating your layout in Interface Builder, then select the layout object in your storyboard or nib and use the Identity Inspector to set the class ALGReversedFlowLayout instead of UICollectionViewFlowLayout.
This should require only iOS6 or higher. (But I have only tested in iOS7.)
There are two ways to use the library in your project:
-
Manually add the library files to your project:
ALGReversedFlowLayout.h ALGReversedFlowLayout.m
-
Using CocoaPods
ALGReversedFlowLayout is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "ALGReversedFlowLayout"
