UICollectionViewLayout subclass for displaying items of different sizes in a grid without wasting any visual space. Inspired by: http://www.crispymtn.com/stories/the-algorithm-for-a-perfectly-balanced-photo-gallery
Mainly three differences to the original:
- It fixes the Issue of upscaled images wich occurs if the partition algorithm assigns a single item to one row.
- Incorporates a fix for a crash on
[UICollectionView insertSections:]from Pull Request #24 - It implements swipe in and out animations, when inserting or removing cells.
Hopefully this can be useful for some of you, if you don't want the animations you can easily remove them in the code: piece 1 and piece 2.
- Tested with iOS 7, but should be compatible with iOS6 as well
- Works with iPhone and iPad
- All interface orientations are supported
The easiest way is to use CocoaPods. If you don't already, here's a guide.
pod 'NHBalancedFlowLayout', '~> 0.2'
If you don't use CocoaPods, you'll need to copy the following files into your project:
- NHBalancedFlowLayout.h
- NHBalancedFlowLayout.m
- NHLinearPartition.h
- NHLinearPartition.m
