FUITextRecognitionViewController

open class FUITextRecognitionViewController : UIViewController

The FUITextRecognitionViewController is convenience controller embedding FUITextRecognitionView view which captures video from device back camera and performs text recognition. For more example to how to configure text recognition check out the FUITextRecognitionView documentation.

## Example Initialization and Configuration

 textRecController = FUITextRecognitionViewController()
 //additional phone number detector to filter out observations
 let detector = try! NSDataDetector.init(types: NSTextCheckingResult.CheckingType.phoneNumber.rawValue)

 var frameCount = 10 //capture the observations after 10 frames
 textRecController.recognitionView.observationHandler = { observations in
    //use NSDataDetector extensions to run matches on observations
    let matches = detector.matches(in: observations)
    textRecController.recognitionView.showTexts(for: observations, with: matches)
    frameCount -= 1
    if frameCount < 0 {
        DispatchQueue.main.async {
            var phoneNumber: String?
            for match in matches where match.resultType == .phoneNumber {
                    phoneNumber = match.phoneNumber
            }
            textView.text = phoneNumber ?? ""
            dismiss(animated: true)
        }
        return true
    }
    return false
}

 textRecController.onClose = {
    dismiss(animated: true)
 }

 present(UINavigationController(rootViewController: textRecController), animated: true)
