    GCKRemoteMediaClient Class Reference

    Overview

    A class for controlling media playback on a Cast receiver.

    This class provides the same functionality as the deprecated GCKMediaControlChannel , which it wraps, but with a more convenient API. The main differences are:

    • Each request is represented by a GCKRequest object which can be tracked with a dedicated delegate.
    • The GCKRemoteMediaClient supports multiple listeners rather than a single delegate.
    Since
    3.0

    Inherits NSObject.
