用户切换电视信号源时在应用上管理GCKDevices [英] Managing GCKDevices on app when user switch TV source

问题描述

iOS的Google Chrome Cast API具有以下设备发现方法

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];

}
在应用程序开始时运行良好，并且设备通常添加到UI中因为我添加了一个侦听器并在 startScan 方法通常运行5秒钟时开始扫描，但是如果现在我从电视切换了信号源或从电视设备 deviceDidGoOffline 拔下了设备， >方法未调用。设备脱机后如何发布通知？

} 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?
