Simple Barcode Scanner with the ability to customize the overlays of the camera view.
A Simple iOS Barcode Scanner using the native AVFoundation with the ability to customize anything you want. There are certain properties that allow for access to structured control of the scanner, as well as functions that act as notifiers for certain events.
Coming Soon to Cocoapods
In order to use this, you should subclass BarcodeScannerViewController. The camera is
added to the sublayer of the view.
In order to receive events, you can override barcodeScannerIsReady() and
barcodeScannerScannedValue(String) which can be both useful
Other helper functions such as startCamera() and stopCamera() are useful to manually
control the usage of the camera and efficiency of your app.
You can also add custom user interface elements on top of the camera by creating a view
and setting the customOverlayView property.
// This will add the 'backButton' on top of the camera
self.customOverlayView = UIView(frame: self.view.frame)
self.customOverlayView?.addSubview(backButton)
Note that the customization flags must be set before the viewDidAppear (on the initialization) of the view controller, and the custom UI property can be set inside the viewDidLoad
This project also allows the user to manually ask for camera permissions (at your own time)
before displaying the native camera access alert by setting shouldAskForPermissions to false
let barcodeScanner = BarcodeScannerDemo()
// Set some properties available to customize
barcodeScanner.shouldAskForPermissions = true // Automatically will ask for camera permissions
barcodeScanner.shouldShowBarcodeRegion = true // Will show a green rectagle over scanned area
barcodeScanner.highlightColor = .greenColor()
barcodeScanner.shouldPauseAfterScannedItem = true // Will pause the camera after barcode has been scanned
You can download and see the Demo for usages.
Requires iOS 8 or greater. Written in Swift 2.0
