Installation

There are two ways to use the library in your project:

1) Manually add the library files to your project

• CCHexagonFlowLayout.h
• CCHexagonFlowLayout.m

2) Using CocoaPods

pod 'CCHexagonFlowLayout'

Usage

Begin with the creation of an instance of the CCHexagonFlowLayout

// Build layout
CCHexagonFlowLayout *layout = [[CCHexagonFlowLayout alloc] init];
layout.delegate = self;

Choose an orientation

layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
// OR
layout.scrollDirection = UICollectionViewScrollDirectionVertical;

Configure these variables according to your own hexagonal cells:

// Should be negative in order to reduce the space between hexagon and obtain the hive effect
layout.minimumInteritemSpacing = -30.0f;

// You must find the correct value to obtain the desired effect
layout.minimumLineSpacing = 10.0f;

// Your cell size as a square
layout.itemSize = CGSizeMake(230, 200);

// The gap is a positive float that will be use to obtain the hive effect
layout.gap = 76.0f;

Default flow layout options can be used for header/footer supplementary views and sections

layout.headerReferenceSize = CGSizeMake(320, 50);
layout.footerReferenceSize = CGSizeMake(320, 50);
layout.sectionInset = UIEdgeInsetsMake(20.0f, 20.0f, 20.0f, 20.0f);

Tests
