iOS7 gave developers a bunch of cool tools. One of them is the ability to read a variety of different types of bar codes from an AVCaptureSession.
The barcode data comes in as metadata of the live AVCaptureSession. Using some of Ray Wenderlich’s tutorial, I wrote a simple app that reads the string of any QRcode and displays it in an alert. The code is posted here:
I also have submitted a new app to the App Store using what I learned. The app enables an iOS user to swap contact information simply by scanning the QR code from another device, similar to how PINs are exchanged in BBM. I’ll definitely write a blog entry upon its approval.
Till next time!
