KSGallerySlidingCollectionView

KSGallerySlidingCollectionView is a collection view menu in the style of UltraVisual.

Reference from RPSlidingMenu.But we make some improve Which makes it a highly-customizable lightweight component.

Description

CollectionViewLayout subclass from FlowLayout directly.
Better performance:we do not caculate layoutattributes of all Items.we only recaculate layoutattributes of rect that needed to display.
Highly-customizable and lightweight.

Demo

see KSGallerySlidingCollectionViewDemo

Installation

From CocoaPods

Add pod 'KSGallerySlidingCollectionView' to your Podfile

Usage

(see sample Xcode project in /KSGallerySlidingCollectionViewDemo)

Create a new file that inherits from KSGallerySlidingCell. overload the following method:
```
 - (void)layoutSubViewsWithPercent:(CGFloat)percentOfGrowth
```

You should do all the position and alpha change dule to the percentOfGrowth

In the ViewController,setup the CollectionView:

 KSGallerySlidingLayout *layout = [[KSGallerySlidingLayout alloc] initWithDelegate:self];
 layout.itemSize = CGSizeMake(CGRectGetWidth(self.collectionView.frame), HomeNewsCellCollapsedHeight);
 self.collectionView.collectionViewLayout = layout;
 [self.collectionView registerNib:[UINib nibWithNibName:@"HomeNewsCell" bundle:nil] forCellWithReuseIdentifier:@"HomeNewsCell"];

Advance Customization

You can customize the featureHeight and collapsedHeight.
set the height after cell intilized:

 self.featureHeight = HomeNewsCellFeatureHeight;
 self.collapsedHeight = HomeNewsCellCollapsedHeight;

implement the KSGallerySlidingLayoutLayoutDelegate in the ViewController:

	- (CGFloat)heightForFeatureCell
	{
	    //    return RPSlidingCellFeatureHeight;
	    return HomeNewsCellFeatureHeight;
	}
	
	- (CGFloat)heightForCollapsedCell
	{
	    //    return RPSlidingCellCollapsedHeight;
	    return HomeNewsCellCollapsedHeight;
	}

Customize the cell animation when view scroll all you need to do is overload the following method in you cell,and do all the position and alpha change dule to the percentOfGrowth:
```
 - (void)layoutSubViewsWithPercent:(CGFloat)percentOfGrowth
```
