## What it is
A small Objective-C library providing a custom zooming view controller transition animation for iOS, similar to the Pinterest-style image expansion effect. It works with UINavigationController push/pop transitions and modal presentations via a simple protocol.

## Use cases
- add a Pinterest-style zoom transition between a collection view and detail view
- animate expanding a thumbnail image into a full-screen view
- customize UINavigationController push transitions with zoom animation
- implement zoom transitions for modal view controllers
- make table view cells zoom into detail screens

## When to choose
- building an iOS app in Objective-C or Swift that needs image zoom transitions
- wanting a lightweight, simple alternative to writing custom view controller transition animators
- needing transitions that work with both navigation stacks and modal presentation

## When to avoid
- building for platforms other than iOS
- needing actively maintained libraries with recent updates (last release 2017)
- requiring SwiftUI-native transition APIs
- needing complex or highly customizable transition choreography beyond zooming
