Overview
A class that manages sessions.
The method startSessionWithDevice: (GCKSessionManager) is used to create a new session with a given GCKDevice. The session manager uses the GCKDeviceProvider for that device type to construct a new GCKSession object, to which it then delegates all session requests.
GCKSessionManager handles the automatic resumption of suspended sessions (that is, resuming sessions that were ended when the application went to the background, or in the event that the application crashed or was forcibly terminated by the user). When the application resumes or restarts, the session manager will wait for a short time for the device provider of the suspended session's device to discover that device again, and if it does, it will attempt to reconnect to that device and re-establish the session automatically.
If the application has created a GCKUICastButton without providing a target and selector, then a user tap on the button will display the default Cast dialog and it will automatically start and stop sessions based on user selection or disconnection of a device. If however the application is providing its own device selection/control dialog UI, then it should use the GCKSessionManager directly to create and control sessions.
Whether or not the application uses the GCKSessionManager to control sessions, it can attach a GCKSessionManagerListener to be notified of session events, and can also use KVO to monitor the connectionState property to track the current session lifecycle state.

Method Detail
- (instancetype) init |
Default initializer is not available.
- (BOOL) startSessionWithDevice: | (GCKDevice *) | device |
Starts a new session with the given device.
This is an asynchronous operation.
- Parameters
-
device The device to use for this session.
- Returns
YES
if the operation has been started successfully,NO
if there is a session currently established or if the operation could not be started.
- (BOOL) suspendSessionWithReason: | (GCKConnectionSuspendReason) | reason |
Suspends the current session.
This is an asynchronous operation.
- Parameters
-
reason The reason for the suspension.
- Returns
YES
if the operation has been started successfully,NO
if there is no session currently established or if the operation could not be started.
- (BOOL) endSession |
Ends the current session.
This is an asynchronous operation.
- Returns
YES
if the operation has been started successfully,NO
if there is no session currently established or if the operation could not be started.
- (BOOL) endSessionAndStopCasting: | (BOOL) | stopCasting |
Ends the current session, optionally stopping casting.
This is an asynchronous operation.
- Parameters
-
stopCasting Whether casting of content on the receiver should be stopped when the session is ended.
- Returns
YES
if the operation has been started successfully,NO
if there is no session currently established or if the operation could not be started.
- (BOOL) hasConnectedSession |
Tests if a session is currently being managed by this session manager, and it is currently connected.
This will be YES
if the session state is GCKConnectionStateConnected.
- (BOOL) hasConnectedCastSession |
Tests if a Cast session is currently being managed by this session manager, and it is currently connected.
This will be YES
if the session state is GCKConnectionStateConnected and the session is a Cast session.
- (void) addListener: | (id< GCKSessionManagerListener >) | listener |
Adds a listener for receiving notifications.
- Parameters
-
listener The listener to add.
- (void) removeListener: | (id< GCKSessionManagerListener >) | listener |
Removes a listener that was previously added with addListener:.
- Parameters
-
listener The listener to remove.
