Installation

CocoaPods

Collection View Layouts is available through CocoaPods. To install it, simply add the following lines (depends on your needs) to your Podfile:

pod 'collection-view-layouts/Core'
pod 'collection-view-layouts/TagsLayout'
pod 'collection-view-layouts/PinterestLayout'
pod 'collection-view-layouts/Px500Layout'
pod 'collection-view-layouts/InstagramLayout'
pod 'collection-view-layouts/FlipboardLayout'
pod 'collection-view-layouts/FacebookLayout'
pod 'collection-view-layouts/FlickrLayout'

Requirements

iOS: 11.0+
Swift: 5.0
CocoaPods: for iOS

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Usage

Configuration of custom layouts is pretty easy:

var layout: BaseLayout = TagsLayout()

layout.delegate = self
layout.delegate = ItemsPadding(horizontal: 10, vertical: 10)
layout.cellsPadding = ItemsPadding(horizontal: 8, vertical: 8)

collectionView.collectionViewLayout = layout
collectionView.reloadData()

Also, you have to implement LayoutDelegate protocol:

public protocol LayoutDelegate: class {
    func cellSize(indexPath: IndexPath) -> CGSize
}

func cellSize(indexPath: IndexPath) -> CGSize {
    return cellsSizes[indexPath.row]
}
