  • Scanning library did output scanning results

    Depending on how you want to treat the result, you might want to dismiss the scanningViewController here.

    This method is the default way for getting access to results of scanning.

    Note:

    • there may be 0, 1, or more than one scanning results.
    • each scanning result belongs to a common MBPRecognizerResult type

    • handle different types differently

    NOTE: This method is called on background processing thread. Make sure that you dispatch all your UI API calls to main thread.
