QRBot

Requirements

iOS 8+

Installation

QRBot is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'QRBot'

Usage

Follow the steps to use QRBot:

1. You need to give permission to access Camera in Info.plist.

2. Make QRCodeScannerViewController superclass of your ViewController class.

 class ViewController: QRCodeScannerViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
    }
 }

3. Conform/ Implement QRCodeScannerDelegate protocol and implement its method to perform your tasks.

 class ViewController: QRCodeScannerViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
    }
 }
 extension ViewController: QRCodeScannerDelegate{
    func scanner(_ connection: AVCaptureConnection, didOutput data: String) {
        print("DemoApp : Data from QR Code - \(data)")
        // Perform your actions here with data from QRCode
    }
 }

( If AVCaptureConnection may show any error, just import AVFoundation in your ViewController. )

 import UIKit
 import AVFoundation
 import QRBot
 
 class ViewController: QRCodeScannerViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
    }
 }
 extension ViewController: QRCodeScannerDelegate{
    func scanner(_ connection: AVCaptureConnection, didOutput data: String) {
        print("DemoApp : Data from QR Code - \(data)")
        // Perform your actions here with data from QRCode
    }
 }

4. Set scannerDelegate property of your ViewController to self.

 class ViewController: QRCodeScannerViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        scannerDelegate = self
    }
 }

5. All set. Now implement your tasks in delegate method.
