## What it is
OAStackView is an Objective-C backport of Apple's UIStackView for iOS 7 and iOS 8, replicating its layout features. It works both in code and Interface Builder and is distributed via CocoaPods.

## Use cases
- use stack views on iOS 7 or 8
- backport UIStackView to older iOS versions
- easily lay out views vertically or horizontally in legacy iOS apps
- replace manual Auto Layout constraints with a stack view
- use stack views from Interface Builder on pre-iOS 9

## When to choose
- you must support iOS 7 or 8 and want UIStackView-like layout
- you maintain a legacy Objective-C codebase that cannot adopt iOS 9 APIs

## When to avoid
- your deployment target is iOS 9 or later (use the native UIStackView)
- you need a maintained library - the project has not been updated since 2017
- you are building in Swift with modern iOS APIs

## Facets
- artifact type: library
