Can Objective C apps make use of barcode scanning or QR code reading capabilities?

Objective C apps can indeed take advantage of barcode scanning and QR code reading capabilities. To implement this functionality, developers can utilize libraries such as ZXingObjC and frameworks like AVFoundation which provide ready-to-use APIs and tools for scanning barcodes and QR codes. Here’s how you can integrate barcode scanning and QR code reading in an Objective C app: Start by adding the library or framework to your project. For example, to use ZXingObjC, you can include it as a dependency using Cocoapods. Import the necessary classes and headers in your view controller or where you want to implement the scanning functionality. Create an instance of the barcode scanner or QR code reader class. Configure the scanner or reader to capture images from the device’s camera and process them. Implement the necessary delegate methods to receive the scanned barcode or QR code data. Handle the retrieved data as per your app’s requirements, such as displaying information or performing specific actions. By following these steps, you can
