ScrollViewCustomHorizontalPageSize

public protocol ScrollViewCustomHorizontalPageSize : UIScrollViewDelegate

Protocol that simplifies custom page size configuration for UIScrollView. Sadly, can not be done better due to protocol extensions limitations - https://stackoverflow.com/questions/39487168/non-objc-method-does-not-satisfy-optional-requirement-of-objc-protocol

Note

Set .decelerationRate to UIScrollViewDecelerationRateFast for a fancy scrolling animation.
