An implementation of QR code encoder for Objective-C ported from Psytec library

branch: master
README.md

Install

To integrate the QR Code Encoder static library with your iOS application, follow the steps below:

  1. Drag the Xcode project package QRCodeEncoderObjectiveCAtGithub.xcodeproj to your project navigator

  2. Click on your project. Choose the target. Then go to the Build Phases page. Expand "Target Dependencies" and add qrencoder to the list

  3. In the same Build Phases page, expand "Link Binary With Libraries", add libqrencoder.a to the list

  4. Switch to the Build Settings page, go down to the Search Paths section. (if you have trouble finding it, type "header search" in the search field) Add the absolute path to the source code directory to the path list.

  5. Add "CoreGraphics" framework to frameworks

  6. Build the project and you are good to go!

Install the Cocoapod

An easier way to make the library available to your project is to use Cocoapods. Assuming you already have Cocoapods installed, here are the instructions:

  1. Open a terminal window, cd to your project's root directory
  2. Run the command:

    touch Podfile
    
  3. Open Podfile in a text editor, add the following lines:

    platform :ios
    pod 'QR-Code-Encoder-for-Objective-C'
    

    save and close the file

  4. Run the command to install:

    pod install
    
  5. Run the command to open the project:

    open NAME_OF_YOUR_PROJECT.xcworkspace
    

How to Use

Here is the typical workflow:

1. Import QREncoder.h

2. Call +[QREncoder encodeWithECLevel:version:string:] to encode a string to a square matrix of booleans.

3. Call +[QREncoder renderDataMatrix:imageDimension:] to render the matrix generated in step 2.

Take a look at QRCodeEncoderDemoViewController.mm for encoding and rendering examples. Or build and run the target QRCodeEncoderDemo to see things in action.

Also, since the encoder references C++ code, ALL implementation files need to have .mm as the extension.
