Protocol

AVAssetResourceLoaderDelegate

Methods you can implement to handle resource loading requests coming from a URL asset.

Declaration

protocol AVAssetResourceLoaderDelegate

Overview

A class should adopt this protocol when associated with the asset’s resource loader—that is, an instance of the AVAssetResourceLoader class. The resource loader works with your delegate to process the request.
