Overview

An AVAssetResourceLoader object mediates resource requests from an AVURLAsset object with a delegate object that you provide. When a request arrives, the resource loader asks your delegate if it is able to handle the request and reports the results back to the asset.

Instance Attribute Details

- (Object) delegate (readonly)

The delegate object to use when handling resource requests. (read-only) The delegate object is responsible for indicating whether or not it is able to handle a resource request. And for those requests it does handle, the delegate object must initiate the loading of the requested resource.

Returns:

- (dispatch_queue_t) delegateQueue (readonly)

The dispatch queue to use when handling resource requests. (read-only) Resource requests are processed synchronously on the specified dispatch queue.

Returns:

  • (dispatch_queue_t)

Instance Method Details

- (Object) setDelegate(delegate, queue:delegateQueue)

Sets the delegate and dispatch queue to use with the resource loader. You use this method to specify the object to use when handling resource requests and the dispatch queue on which to process those requests. Resource requests are processed synchronously on the dispatch queue you provide.

Parameters:

  • delegate (Object)

    The delegate object to query when handling resource requests. You may specify nil if you want to clear the delegate object. The resource loader does not store a strong reference to the delegate object.

  • delegateQueue (dispatch_queue_t)

    The dispatch queue on which to execute resource requests. If the delegate parameter is not nil, this parameter must also not be nil and must contain a valid dispatch queue. However, if delegate is nil, this parameter may also be nil. The resource loader maintains a strong reference to the dispatch queue you specify.

Returns:
