ZBarReaderViewDelegate Protocol Reference
=========================================
.. class:: ZBarReaderViewDelegate
:Inherits from: :class:`NSObject`
This protocol, which must be implemented by the `readerDelegate` provided
to a :class:`ZBarReaderView`, is used to notify the delegate of new decode
results.

asynchronously being converted to a :class:`UIImage`, attempting to
access the data will block until the conversion is complete.

:symbols: :class:`ZBarSymbolSet` containing the decode results.
:image: :class:`UIImage` from which the barcode(s) were scanned.
