Thanks for asking! ZLBalanceFlowLayout is a subclass of UICollectionViewFlowLayout which is available since iOS 6. But it is written in Swift and cocoapod's support for Swift project requires at least iOS 8. So if you want to use ZLBalanceFlowLayout in deployment target before iOS 8, I would suggest you to download the source and add it to your project manually.
