EventsController
EventsController allows you subscribe to the system events published by the SDK.
Publishers in EventsController
The allEventsPublisher will emit a new value every time an event is published by the SDK.
The EventsController also allows you to subscribe to specific events using the public func eventPublisher<T: Event>(_ eventType: T.Type) method.
This method returns a publisher that can be used to observe a specific event of type T.
// Subscribe for `MessageUpdatedEvent`
eventsController
.eventPublisher(MessageUpdatedEvent.self) // The type of the event you want to observe
.filter { [messageId = messageController.messageId] in
$0.messageId == messageId
}
.sink {
print($0) // Process the update to the message
}
.store(in: &cancellables)Example: Subscribing to the MessageNewEvent
class YourCustomChannelListVC: ChatChannelListVC {
var eventsController: EventsController!
var cancellables: Set<AnyCancellable> = []
override func viewDidLoad() {
super.viewDidLoad()
eventsController = controller.client.eventsController()
eventsController
.eventPublisher(MessageNewEvent.self)
.receive(on: RunLoop.main)
.sink { messageNewEvent in
// do what you need with the event
print(messageNewEvent.messageId)
}
.store(in: &cancellables)
}
