iOS Gallery scan
The SDK allows you to decode barcodes from image files. It supports several image formats, including BMP, PNG, and JPG. The config you pass must be made with your license key, BarkoderConfig(licenseKey:licenseCheckHandler:), as in the example below.
Swift
BarkoderHelper.scanImage(image, bkdConfig: bkdConfig, resultDelegate: self)Here is an example of how you can access the photo library on your device and select and scan images from within the library:
Swift
extension ViewController: UIImagePickerControllerDelegate & UINavigationControllerDelegate {
func presentImagePicker() {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .photoLibrary
UINavigationBar.appearance().backgroundColor = .white
UIBarButtonItem.appearance().tintColor = .black
self.present(imagePicker, animated: true) {
UINavigationBar.appearance().backgroundColor = .clear
UIBarButtonItem.appearance().tintColor = .white
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
picker.dismiss(animated: true, completion: nil)
guard let image = info[.originalImage] as? UIImage else {
return
}
// the license key is needed here too: a BarkoderConfig() without it has no decoder
let bkdConfig = BarkoderConfig(licenseKey: "LICENSE_KEY") { licenseResult in
print("Licensing SDK: \(licenseResult.message ?? "")")
}
BarkoderHelper.applyConfigSettingsFromTemplate(bkdConfig, template: .gallery_scan) { config in
BarkoderHelper.scanImage(image, bkdConfig: config, resultDelegate: self)
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
}
