EFQRCode is a lightweight, pure-Swift library for generating stylized QRCode images with watermark or icon, and for recognizing QRCode from images, inspired by qrcode. Based on CoreGraphics, CoreImage, and ImageIO, EFQRCode provides you a better way to handle QRCode in your app, no matter if it is on iOS, macOS, watchOS, and/or tvOS. You can integrate EFQRCode through CocoaPods, Carthage, and/or Swift Package Manager.

Examples

Demo Projects

App Store

You can click the App Store button below to download demo, support iOS, tvOS and watchOS:

You can also click the Mac App Store button below to download demo for macOS:

Compile Demo Manually

To run the example project manually, clone the repo, demos are in the ‘Examples’ folder, remember run command sh Startup.sh in terminal to get all dependencies first, then open EFQRCode.xcworkspace with Xcode and select the target you want, run.

Or you can run the following command in terminal:

Requirements

Version	Needs
1.x	Xcode 8.0+ Swift 3.0+ iOS 8.0+ / macOS 10.11+ / tvOS 9.0+
4.x	Xcode 9.0+ Swift 4.0+ iOS 8.0+ / macOS 10.11+ / tvOS 9.0+ / watchOS 2.0+
5.x	Xcode 11.1+ Swift 5.0+ iOS 8.0+ / macOS 10.11+ / tvOS 9.0+ / watchOS 2.0+
6.x	Xcode 12.0+ Swift 5.1+ iOS 9.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+

Installation

CocoaPods

EFQRCode is available through CocoaPods. To installit, simply add the following line to your Podfile:

Then, run the following command:

Carthage

IMPORTANT: this workaround is necessary for Carthage to somewhat work in Xcode 12.

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

To integrate EFQRCode into your Xcode project using Carthage, specify it in your Cartfile:

Run carthage update to build the framework and drag the built EFQRCode.framework into your Xcode project.

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.

Once you have your Swift package set up, adding EFQRCode as a dependency is as easy as adding it to the dependencies value of your Package.swift.

Quick Start

1. Import EFQRCode

Import EFQRCode module where you want to use it:

2. Recognition

A String Array is returned as there might be several QR Codes in a single CGImage:

3. Generation

Create QR Code image, basic usage:

Parameter	Description
`content`	*REQUIRED*, content of QR Code
`size`	Width and height of image
`backgroundColor`	Background color of QRCode
`foregroundColor`	Foreground color of QRCode
`watermark`	Background image of QRCode

Result:

4. Generation from GIF

Use EFQRCode.generateGIF to create GIF QRCode.

Parameter	Description
`generator`	*REQUIRED*, an `EFQRCodeGenerator` instance with other settings
`data`	*REQUIRED*, encoded input GIF
`delay`	Output QRCode GIF delay, emitted means no change
`loopCount`	Times looped in GIF, emitted means no change

You can get more information from the demo, result will like this:

Recommendations

Please select a high contrast foreground and background color combinations;
To improve the definition of QRCode images, increase size, or scale up using magnification (instead);
Magnification too high／size too large／contents too long may cause failure;
It is recommended to test the QRCode image before put it into use;
You can contact me if there is any problem, both Issue and Pull request are welcome.
