@interface SBSDKGenericTextLineRecognizerViewController
    : SBSDKBaseScannerViewController

A UIViewController subclass to show a camera screen with the text line recognizer. A view finder like rectangle shows the area where text is recognized. The camera can be zoomed in and out using an action or a double-tap to make aiming at the desired area easier. Once some text is recognized within the view finder area, the result is delivered to the receivers delegate. A customizable validation routine checks validates the result and sets a flag in the result.
