<GCKMediaQueueDelegate> Protocol

  • The GCKMediaQueueDelegate protocol is used for receiving asynchronous notifications from a GCKMediaQueue.

  • This protocol includes methods to notify when the queue is about to change, has been reloaded, or when items are inserted, updated, or removed.

  • The delegate methods provide information about the specific changes made to the queue, such as the range of inserted items or the indexes of updated or removed items.

  • The mediaQueueDidChange method is called after any queue changes have been completed.
