DOBCaptureViewController

This class initialises a QR or Barcode reader View in iOS7 and provides a reusable ViewController in order to display it modally wherever you want.

It is based on this tutorial from invasivecode

Right now is just a proof of concept. I have in mind add more options like selecting the type of codes you want, select if you want flash and vibration switch or not and others...

How does it work

DOBCaptureViewController is a UIViewController subclass that adds a layer controlling the device's back camera in order to read QR and barcodes through Apple's native API.

It will return the data through codeCaptured: method in DOBCaptureDelegate

Sample

In order to open the DOBCaptureViewController as modal view just add this piece of code

        _captureViewController = [[DOBCaptureViewController alloc] init];
        [_captureViewController setCloseAfterRead:YES];
        [_captureViewController setDelegate:self];

        UIBarButtonItem* button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(closeCapture:)];
        [_captureViewController.navigationItem setLeftBarButtonItem:button];

        UINavigationController* nav = [[UINavigationController alloc] initWithRootViewController:_captureViewController];
        [nav.navigationBar setTranslucent:NO];
        [self presentViewController:nav animated:YES completion:nil];

In the closeCapture: method is up to you to dismiss the view.

The view has the option setCloseAfterRead that will automatically dismiss the view for you when the code has been read and returned.
