Managing GCKDevices on app when user switch TV source

问题

Google Chrome cast api of ios have the following methods of device discovery

- (void)deviceDidComeOnline:(GCKDevice *)device {


// : manipulate UI
[self.tableView reloadData];

}

- (void)deviceDidGoOffline:(GCKDevice *)device {

//: manipulate UI 
[self.tableView reloadData];

} this runs fine at the start of application and the devices are added to UI normally because I add a listener to it and start the scan when startScan method that typically runs for 5 seconds but if now i switch the source from TV or unplug the device from TV device deviceDidGoOffline method is not called. How can I have a notification posted once the device have gone offline?

There is currently a bug in the SDK which affects this feature. It will be addressed in the next release.
