The QRCodeReaderViewController is a simple QRCode and bar code 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.
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.
Install CocoaPods if not already available:
$ [sudo] gem install cocoapods
$ pod setupGo 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', '~> 3.0.0'Install into your project:
$ pod installOpen your project in Xcode from the .xcworkspace file (not the usual project file)
$ open MyProject.xcworkspaceDownload 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.
- (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];
}

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

[self dismissViewControllerAnimated:YES completion:NULL];
