## What it is
TOCropViewController is an open-source iOS view controller for cropping UIImage objects and performing basic rotations, designed to feel like the iOS Photos app editor. A Swift wrapper, CropViewController, provides a more native Swift interface.

## Use cases
- crop images in an iOS app
- let users edit profile pictures
- crop photos to a specific aspect ratio
- rotate images in 90-degree increments
- create circular cropped avatars
- share cropped portions of a photo

## When to choose
- building an iOS app that needs user-facing image cropping
- you want a familiar Photos-app-style cropping UX
- you need aspect ratio clamping, rotation, and circular cropping out of the box
- you want a library localized in many languages

## When to avoid
- building for platforms other than iOS
- you need advanced photo editing like filters or video editing
- your project requires programmatic server-side image cropping
- you need cross-platform (Flutter/React Native) cropping UI

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, ui-components
- domain: image-processing, mobile-development, media
- platform: -
- tags: image-cropping, uikit, view-controller, objective-c, cocoapods, swift-package-manager, photo-editing, ios, swift, mobile
