Parchment

Parchment is a very flexible paging view controller. It let’s you page between view controllers while showing any type of generic indicator that scrolls along with the content.

Here are some benefits of using Parchment:

• Memory-efficient: Parchment only allocates view controllers when they’re needed, meaning if you have a lot of view controllers you don’t have to initialize them all up-front.
• Infinite scrolling: Because view controllers are only allocated as you are scrolling, you can create data sources that are infinitely large. This is perfect for things like calendars.
• Highly customizable: The menu items are built using UICollectionView, which means you can display pretty much whatever you want. You can even subclass the layout to create completely custom behaviours.
