# AVAssetResourceLoaderDelegate

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

## Declaration

```swift
protocol AVAssetResourceLoaderDelegate : NSObjectProtocol
```

## Overview

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.
