Ready to take off? Let’s begin by launching the Xcode. Therefore, you’ll need to connect your device and run it there if you want to see the application live. Note that this application cannot be tested on the Simulator, neither to a device without a camera, as everything is based on real-time video capturing.

Some typical content examples of a QR Code are: A QR Code can store a great amount of data (in relation to the ordinary barcode), so there is a variety of information that can be encoded in it. The data that’s being encapsulated into such a code, is read by devices specificly designed for this job, or by smart devices (smartphones, tablets) using the appropriate software. Instead of the vertical lines like those that the well-known barcode contains, a QR Code can have its lines designed in both horizontal and vertical directions. One of the new features that the AVFoundation incorporates, is the ability to discover and read bar codes in real-time, and one of the supported bar code types that we especially interested in at this tutorial, is the QR Code.Ī Quick Response Code (QR Code) is actually a two-dimensional (2D) barcode. The AVFoundation framework is just one of them, as it has accepted great enhancements and new class additions that make even more tools available. Both major additions and minor improvements have been made, offering developers new or updated frameworks and APIs to work with, and the opportunity to provide single users with a much richer experience. IOS 7 brings a wealth of new features that set it apart from all other mobile operating systems.
