# QR Code Scanner for iOS
Scans QR codes using the device's camera and returns a string value.
## Installation
1. Install [CocoaPods](https://cocoapods.org).
2. Add the following dependency in your **Podspec** file:
~~~ruby
pod 'QR-Code-Scanner-iOS', '~> 1.0'
~~~
3. Run `pod install`.
## Usage
~~~swift
import UIKit
import QRCodeScanner
class MyViewController: UIViewController, QRCodeScanViewControllerDelegate {
/// Start the QR code scan
func scanQRCode() {
// Create an instance of QRCodeScanViewController
let viewController = QRCodeScanViewController.create()
// Set itself as delegate
viewController.delegate = self
// Present the view controller
self.present(viewController, animated: true)
}
// MARK: QRCodeScanViewControllerDelegate
/// Called when the camera scans a QR code
/// - Parameters:
/// - viewController: View controller that scanned the QR code
/// - value: String encoded in the QR code
func qrCodeScanViewController(_ viewController: QRCodeScanViewController, didScanQRCode value: String) {
// Dismiss the view controller
viewController.dismiss(animated: true) {
// Show an alert with the scanned value
let alert = UIAlertController(title: "Scanned value", message: value, preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true)
}
}
}
~~~
