The AVQRCodeReader is a simple QRCode reader. It is based on the AVFoundation framework from Apple.
Download the project and copy the AVQRCodeViewController folder into your project and then simply #import "AVQRCodeViewController.h" in the file(s) you would like to use it in.
To initialize an instance of AVQRCodeViewController:
objective-c
AVQRCodeViewController *qrVC = [[AVQRCodeViewController alloc] initWithDismissBlock:^(AVQRCodeViewController *qrViewController, NSString *scannedValue) {
NSLog(@"Value : %@", scannedValue);
[qrViewController dismissViewControllerAnimated:YES completion:nil];
}];
[self presentViewController:qrVC animated:YES completion:nil];
