Introduction

DMScrollViewStack is a UIScrollView subclass that efficently handles a vertical stack of multiple sub views/scrollviews. With this class you can make a single scrollview composed by multiple views, tables or collection views without losing in performances or waste your device’s memory.

A more detailed description of this class and how it works under the hood can be found in my blog's article here: "How to efficiently handle a stack of scroll views in iOS"

Usage

Usage is pretty simple. You can use exposed methods to add or remove subviews. Subviews can be straight UIView or UIScrollView subclasses.

-setViews: // set a subview list (no animation)
-addSubview:animated:completion: // add subview at the bottom
-insertSubview:atIndex:animated:completion: // insert subview
-removeSubviewAtIndex:animated:completion: // remove subview

Requirements

I've created it in iOS 8 but it should also works in previous iOS versions without changes.
