## Overview
ScrollingContentViewController makes it easy to create a view controller with a single scrolling content view, or to convert an existing static view controller into one that scrolls. Most importantly, it takes care of several tricky undocumented edge cases involving the keyboard, navigation controllers, and device rotations.

Most importantly, it takes care of several tricky undocumented edge cases involving the keyboard, navigation controllers, and device rotations.
## Background
A common UIKit Auto Layout task involves creating a view controller with a fixed layout that is too large to fit older, smaller devices, or devices in landscape orientation, or the area of the screen that remains visible when the keyboard is presented. The problem is compounded when [Dynamic Type](https://developer.apple.com/documentation/uikit/uifont/scaling_fonts_automatically) is used to support large font sizes.

This case can be handled by nesting the view inside a scroll view. You could do this manually in Interface Builder, as described by Apple's [Working with Scroll Views](https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/AutolayoutPG/WorkingwithScrollViews.html) documentation, but many steps are required. If your view contains text fields, you'll have to write code to adjust the view to compensate for the presented keyboard, as described in [Managing the Keyboard](https://developer.apple.com/library/archive/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW3). However, handling the keyboard robustly is [surprisingly complicated](#keyboard-resize-filtering), especially if your app presents a sequence of screens with keyboards in the context of a navigation controller, or when device orientation support is required.
To simplify this task, ScrollingContentViewController inserts the scroll view into the view hierarchy for you at run time, along with all necessary Auto Layout constraints.
To simplify this task, ScrollingContentViewController inserts the scroll view into the view hierarchy for you at run time, along with all necessary Auto Layout constraints.
When used in a storyboard, ScrollingContentViewController exposes an outlet called [`contentView`](#contentView) that you connect to the view that you'd like to make scrollable. This may be the view controller's root view or an arbitrary subview. Everything else is taken care of automatically, including responding to keyboard presentation and device orientation changes.

During a device orientation transition, a [`keyboardWillHide`](https://developer.apple.com/documentation/uikit/uikeyboardwillhidenotification) notification is posted before the animation starts, followed by [`keyboardWillShow`](https://developer.apple.com/documentation/uikit/uiresponder/1621576-keyboardwillshownotification) after it ends, even though the keyboard remains visible during the transition. Because the duration of the animation exceeds the filtering time window, it is therefore necessary to temporarily suspend filtering during the transition. Otherwise, the content view would resize unnecessarily.
Finally, ScrollingContentViewController correctly handles the case where changes to the size or layout of the scroll view's content may occur in response to keyboard presentation or device orientation changes (in particular when [`shouldResizeContentViewForKeyboard`](#shouldResizeContentViewForKeyboard) is `true`), invaliding the coordinate space of the rectangle passed to [`scrollRectToVisible`](https://developer.apple.com/documentation/uikit/uiscrollview/1619439-scrollrecttovisible) (most importantly, in the case when that method is called automatically by iOS after keyboard changes) which would otherwise result in the scroll view scrolling by an inappropriate amount or leaving the scroll view with a content offset that is outside of the legal scrolling range.
