<GCKUIImagePicker> Protocol

  • GCKUIImagePicker is a protocol used for selecting images from GCKMediaMetadata for display in the Google Cast user interface.

  • A default implementation selects the first image from the metadata, but applications can provide a custom implementation for more nuanced image selection.

  • The getImageWithHints:fromMetadata: method is the core functionality, allowing developers to retrieve an image based on specified criteria (hints) from the metadata.

  • By setting the GCKCastContext::imagePicker property, developers can customize how images are selected for their Cast application's UI elements.
