Protocol

AVCaptureMetadataOutputObjectsDelegate

Methods for receiving metadata produced by a metadata capture output.

Overview

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.
