A collectionViewLayout layout cells like waterfall, which add the missing collectionViewHeader and collectionViewFooter.

LXMWaterfallLayout is inspired by CHTCollectionViewWaterfallLayout, and made several improvements to make it easier to use. It is subclass of UICollectionViewLayout and it's usage is just like UICollectionViewFlowLayout.

传送门和传送门是我写的总结

Swift3.0 +
Xcode8.0 +

1, CocoaPods
add pod 'LXMWaterfallLayout' to your podfile and run pod install
2, Manual
drag LXMWaterfallLayout.swift into your project

1.0.6

• add LXMHorizontalMenuLayout;

1.0.4

• update to Swift4.2，Swift4.1 and before please use 1.0.3

1.0.3

• Fix a bug

1.0.0

• Add horiziontalAlignment and verticalAlignment property, which make LXMWaterfallLayout supports alignment now;
• Add support for UICollectionViewScrollDirection.horizontal

0.0.4

• Fix bugs with contentInset

0.0.3

• Add LXMLayoutHeaderFooterProtocol and LXMHeaderFooterFlowLayout
  Now both LXMHeaderFooterFlowLayout and LXMWaterfallLayout confirm to LXMLayoutHeaderFooterProtocol so the architecture is more clear, what's more, if you have your own collectionViewLayout and you want it to have a header or footer too, you can complete it in minutes by adopting LXMLayoutHeaderFooterProtocol

It is just like UICollectionViewFlowLayout, all you have to do is LXMWaterfallLayout() and assign it to a collectionView

if (find any bug || have any problem) {
   feel free to open an issue or pull request
} else {
   star it if it helps
}

I will try my best to help as soon as I see it~
