QRCodeReaderViewController

The QRCodeReaderViewController was initialy a simple QRCode reader but it now lets you the possibility to specify the format type you want to decode. It is based on theAVFoundationframework from Apple in order to replace ZXing or ZBar for iOS 7 and over.

It provides a default view controller to display the camera view with the scan area overlay and it also provides a button to switch between the front and the back cameras.

Installation

The recommended approach to use QRCodeReaderViewController in your project is using the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.

CocoaPods

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods  $ pod setup

Go to the directory of your Xcode project, and Create and Edit your Podfile and add QRCodeReaderViewController:

$ cd /path/to/MyProject  $ touch Podfile  $ edit Podfile source 'https://github.com/CocoaPods/Specs.git' platform :ios, '7.0' pod 'QRCodeReaderViewController', '~> 3.5.2'

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file)

$ open MyProject.xcworkspace

Manually

Download the project and copy theQRCodeReaderViewControllerfolder into your project and then simply#import "QRCodeReaderViewController.h"in the file(s) you would like to use it in.
