## What it is
MGSplitViewController is an Objective-C replacement for Apple's UISplitViewController on iPad, adding enhancements like toggleable master visibility, vertical/horizontal split orientation, draggable dividers, and customizable divider views. It mimics UISplitViewController's appearance and delegate API while offering greater layout flexibility.

## Use cases
- build a master-detail iPad interface with a resizable split
- show or hide the master pane independently in portrait and landscape
- create a horizontal master-above-detail layout on iPad
- let users drag the divider between master and detail views
- customize the divider appearance between split view panes
- use a split view controller from a xib with Interface Builder outlets

## When to choose
- you maintain a legacy Objective-C iPad app needing split-view features UISplitViewController lacked in older iOS versions
- you need draggable or horizontally oriented splits unavailable in the stock control
- you want a drop-in UISplitViewController replacement with a compatible delegate API

## When to avoid
- you are starting a new iOS project, since modern UISplitViewController covers most of these features
- you need Swift-first or actively maintained code
- you require Interface Builder visual configuration or SwiftUI support
- you need a guaranteed license for commercial use, as the repo lists no formal license
