AVCaptureMetadataOutputObjectsDelegate
Methods for receiving metadata produced by a metadata capture output.
Declaration
protocol AVCaptureMetadataOutputObjectsDelegate : NSObjectProtocolOverview
The AVCaptureMetadataOutputObjectsDelegate protocol must be adopted by the delegate of an AVCaptureMetadataOutput object. The single method in this protocol is optional. The method allows a delegate to respond when a capture metadata output object receives relevant metadata objects through its connection.
The AVCaptureMetadataOutput object calls the methods of the delegate object on the dispatch queue associated with its metadataObjectsCallbackQueue property.
