A class containing global objects and state for the framework.
The context must be initialized early in the application's lifecycle via a call to setSharedInstanceWithOptions: (GCKCastContext).
Inherits NSObject.
Sets the shared instance, supplying a Cast options object.
If the shared instance is already initialized, an exception will be thrown.
Sets the shared instance, supplying a Cast options object.
The call will fail if the context is already initialized. This method must be called on the main thread.
YES on success, NO on failure.
Returns the singleton instance.
If a shared instance has not yet been initialized, an exception will be thrown.
+ (BOOL) isSharedInstanceInitializedTests if the singleton instance has been initialized yet.
Registers a device provider, which adds support for a new type of (non-Cast) device.
Unregisters the device provider for a given device category.
Sets the credentials data of the current user.
You should call this API with the current user information before starting a cast session and whenever user account is changed.
The credentials data will be embedded in the launch request. If it is to launch an Android TV app, the app can use the credentials data to determine if the app supports this specific user. If not, the cast app will be launched instead.
If an Android TV app is launched, the credential data will be passed to the app, within the launch intent. The app can use this data to personalize the user experience.
If it has not been shown before, presents a fullscreen modal view controller that calls attention to the Cast button and displays some brief instructional text about its use.
YES if the view controller was shown, NO if it was not shown because it had already been shown before. Since version 4.1, NO is also returned if the Cast Button was not found.
Provided by category GCKCastContext(UI).
- (BOOL) presentCastInstructionsViewControllerOnceWithCastButton: (GCKUICastButton *) castButtonIf it has not been shown before, presents a fullscreen modal view controller that calls attention to the Cast button, whose view is passed in, and displays some brief instructional text about its use.
YES if the view controller was shown, NO if it was not shown because it had already been shown before. NO is also returned if the Cast Button was not found.
Provided by category GCKCastContext(UI).
- (void) clearCastInstructionsShownFlagClears the persistent flag that tracks whether the Cast instructions modal view controller has been shown.
Provided by category GCKCastContext(UI).
- (void) presentDefaultExpandedMediaControlsDisplays the default Cast expanded media controls.
Provided by category GCKCastContext(UI).
- (NSString* const) kGCKNotificationKeyCastStateThe userInfo key for the new Cast state in a Cast state change notification.
The name of the notification that will be published when the Cast state changes.
- (NSString* const) kGCKExpandedMediaControlsTriggeredNotificationThe name of the notification that will be published when the expanded media controls should be presented to users.
- (NSString* const) kGCKUICastDialogWillShowNotificationThe name of the notification that will be published when the Cast dialog is about to be shown.
The name of the notification that will be published when the Cast dialog has been dismissed.
The discovery manager.
This object handles the discovery of receiver devices.
The session manager.
This object manages the interaction with receiver devices.
The image cache implementation that will be used by the framework to fetch images that are referenced in media metadata.
A default implementation will be used if one is not provided by the application. May be set to nil to reinstate the default image cache.
Provided by category GCKCastContext(UI).
The image picker implementation that will be used to select an image for a specific purpose.
A default implementation will be used if one is not provided by the application. May be set to nil to reinstate the default image picker.
Provided by category GCKCastContext(UI).
- (BOOL) useDefaultExpandedMediaControls readwritenonatomicassignThe instance of the default Cast expanded media controls view controller.
