RESTfunc eventsController(_ controller: EventsController, didReceiveEvent event: Event)Listening to Events
EventsController
EventsController allows you to subscribe to chat events. You can receive all events or only to events for a specific channels.
Events Controller Delegate
Classes that conform to the EventsControllerDelegate protocol can be used to receive events from the controller.
Client Events
let eventsController: EventsController = client.eventsController()Channel Events
let eventsController: EventsController = channel.eventsController()Example: Local Notifications
In this example we create a custom ChatChannelListVC that shows a local notification every time a new message event is received.
class DemoChannelListVC: ChatChannelListVC, EventsControllerDelegate { lazy var eventsController: EventsController = controller.client.eventsController() override func viewDidLoad() { super.viewDidLoad() eventsController.delegate = self } func eventsController(_: EventsController, didReceiveEvent event: Event) { guard let event = event as? MessageNewEvent else { return } let message = event.message let content = UNMutableNotificationContent() content.title = "\(message.author.name ?? message.author.id) @ \(event.channel.name ?? event.channel.cid.id)" content.body = message.text let request = UNNotificationRequest( identifier: message.id, content: content, trigger: nil ) UNUserNotificationCenter.current().add(request) { error in if let error = error { log.error("Error when showing local notification: \(error)") } } } }
