BouncyLayoutOC

This project is inspired by roberthein's project BouncyLayout, I just implement it by Objective-C.

When I use OC to implement it, compare with the swift code, obviously swift is more readable and compact!

It's time to learn Swift now!

How to use

Clone or download this project, copy HWBouncyLayout.h & HWBouncyLayout.m files into your project.

Import HWBouncyLayout.h, init the layout.

- (instancetype)init;
- (instancetype)initWithStyle:(BouncyLayoutStyle)style;
- (instancetype)initWithDamping:(CGFloat)damping frequency:(CGFloat)frequency;

The param damping and frequency is UIAttachmentBehavior prop, by default:

damping = 0.7

frequency = 1.5

self.layout = [HWBouncyLayout new];
// config the layout...
self.layout.scrollDirection = UICollectionViewScrollDirectionVertical;
// init Collection wiht this layout.
self.collectionView = [[UICollectionView alloc] initWithFrame:self.view.bounds collectionViewLayout:self.layout];
