KScanCamera

适用于 iOS 的二维码扫描组件，使用 Swift 语言实现，支持界面定制，支持取景框，支持 iPhone、iPad，支持方向旋转，支持闪光灯，可从相册选择二维码图片进行识别（需要引入 TZImagePickerController）。

用法

class ViewController: UIViewController {

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

@IBAction func scan(_ sender: Any) {
    let instance = KScanCameraViewController.instance
    instance.cancelEvent = .pop
    instance.didReceiveCode = {(code: String) -> Void in
        print("----received code: \(code)")
        self.navigationController?.popViewController(animated: true)
    }
    instance.didCancel = {
        print("----canceled")
    }
    var config = KScanCameraConfig()
    config.title = "二维码"
    config.message = "将二维码放入扫描框内，即可自动识别"
    config.isAlbumHidden = false
    config.preset = .hd1920x1080
    config.cameraAccessMsg = "相机访问权限被禁用，请启用APP对相机的访问权限"
    instance.config = config
    self.navigationController?.pushViewController(instance, animated: true)
}
