A UICollectionViewLayout subclass that adds custom transitions/animations to the UICollectionView without effecting your existing code.

AnimatedCollectionViewLayoutObjC

Normally a UICollectionView has no transition effects when you scroll from one item to another. There are lots of ways to write animations for UICollectionView, but using a UICollectionViewLayout subclass is by far the simplest one. And it doesn't break any of your existing code. You can still use your UICollectionView subclass and you don't need to change your UICollectionViewCell. Just plug and enjoy.

This Layout was written by Object-C base on the >AnimatedCollectionViewLayout. And add two kinds of animte Move In and Move out.

Warning

This layout just work with UICollectionViewScrollDirectionHorizontal.

Demo

Parallax	ZoomInOut	RotateInOut	Cards
CrossFade	Cube	Page	Move In
Move Out	No animate

Example

To run the example project, clone the repo, and start iOS Example in Xcode.

Requirements

• iOS 7.0+

Usage

Get Started

Import the library where you want to use it. Create a HorizontalFlowLayout object, set its animator and assign it to your UICollectionView.

  HorizontalFlowLayout *lay = [HorizontalFlowLayout new];
  lay.scrollDirection = UICollectionViewScrollDirectionHorizontal;  
  lay.animator = [ParallaxAttributesAnimator new];
  lay.shouldReLayout = YES;
  UICollectionView *collect = [[UICollectionView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT) collectionViewLayout:lay];

Customization

Most of the built-in animators work best in Paging mode and they have additional parameters that you can tweak for better transitions. You can also write your own animators by implementing the protocol LayoutAttributesAnimator.
