QRCodeReaderViewController

This fork is just inteded to add an alert view asking user permission to use the camera on iOS 7 and 8 if he already refused it.

The QRCodeReaderViewController is a simple QRCode Reader/Scanner based on the AVFoundation framework from Apple. It aims to replace ZXing or ZBar for iOS 7 and over.

It also allows you 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', '~> 2.0.0'

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

Usage

- (IBAction)scanAction:(id)sender
{
  QRCodeReaderViewController *reader = [QRCodeReaderViewController new];
  reader.modalPresentationStyle      = UIModalPresentationFormSheet;
  
  // Using delegate methods
  reader.delegate                    = self;
  
  // Or by using blocks
  [reader setCompletionWithBlock:^(NSString *resultAsString) {
    [self dismissViewControllerAnimated:YES completion:^{
      NSLog(@"%@", result);
    }];
  }];

  [self presentViewController:reader animated:YES completion:NULL];
}

#pragma mark - QRCodeReader Delegate Methods

- (void)reader:(QRCodeReaderViewController *)reader didScanResult:(NSString *)result
{
  [self dismissViewControllerAnimated:YES completion:^{
    NSLog(@"%@", result);
  }];
}
