SGQRCode R
An easy-to-use iOS library for scanning, generating, and reading QR codes and barcodes with high customizability.
What is SGQRCode R?
SGQRCode is an iOS library that enables developers to integrate QR code and barcode scanning, generation, and image recognition into their apps. It solves the problem of implementing complex camera-based code interactions by providing a simple, customizable API built on Apple's AVFoundation framework.
iOS developers building apps that require QR/barcode functionality, such as payment apps, inventory systems, event check-ins, or any application needing code-based data exchange.
Developers choose SGQRCode for its comprehensive feature set, high customizability of the scanning UI, and straightforward integration via CocoaPods or manual inclusion, reducing development time compared to building from scratch.
Overview
The easy to use bar code and QR code scan library for iOS【支持二维码生成、读取图片中二维码、条形码和二维码扫描】
Use Cases
Best For
- Adding QR code scanning to payment or ticketing iOS apps
- Building inventory management apps with barcode scanning
- Creating event apps with QR code check-in functionality
- Implementing QR code generation for sharing data or links
- Reading QR codes from saved images in photo libraries
- Developing custom scanning interfaces with unique designs
Not Ideal For
- Cross-platform applications needing Android or web support alongside iOS
- Projects requiring barcode detection from static images, as image recognition only supports QR codes
- SwiftUI-only apps without UIKit interoperability layers
Pros & Cons
Pros
Supports real-time QR code and barcode scanning, generation with logo embedding, and image-based QR code reading, as detailed in the Key Features section.
Allows full customization of the scanning interface through SGScanViewConfigure and SGScanView classes, enabling it to match any app design, as shown in the integration code.
Includes automatic torch control based on ambient light, permission handling via SGPermission, and manual focus, streamlining common scanning tasks without extra code.
Can be added via CocoaPods with 'pod SGQRCode' or manually, with clear setup steps and code snippets provided in the README for quick implementation.
Cons
The library's image recognition only detects QR codes in images, not barcodes, as admitted in the problem section where CIDetector limitations are noted.
Built exclusively for UIKit with iOS 9.0+ or 11.0+ support, making it unsuitable for modern SwiftUI projects without additional wrappers or integration efforts.
Different versions use Block (3.5x) or Delegate (4.x) patterns, leading to potential confusion and migration hurdles, as highlighted in the version table and update notes.
