## What it is
SGQRCode is an easy-to-use iOS library for scanning barcodes and QR codes, generating QR codes, and recognizing QR codes from images. It provides customizable scan views, camera/photo permission handling, and flashlight control based on ambient light.

## Use cases
- scan QR codes with the iOS camera
- generate QR codes with a custom logo
- recognize a QR code from an image in the photo library
- build a customizable barcode scanning screen
- toggle flashlight automatically based on ambient brightness
- handle camera and photo library permission checks

## When to choose
- you need a ready-made, customizable QR/barcode scanner for an iOS app
- you want QR code generation with optional logo overlay
- you prefer an Objective-C library with CocoaPods integration

## When to avoid
- you need to recognize barcodes from images (only QR codes supported from images)
- your project is not iOS/UIKit based
- you need cross-platform scanning support

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, computer-vision
- domain: mobile-development
- platform: -
- tags: qrcode, barcode, scanner, objective-c, cocoapods, camera, torch, qr-generation, ios, swift, mobile
