TPEventBus

TPEventBus is a publish/subscribe event bus for iOS, inspired by EventBus and QTEventBus.

EventBus in 3 steps

Define events:

class TPCountEvent: NSObject, TPEvent {
	var count: Int

    init(count: Int) {
        self.count = count
    }
}

Prepare subscribers:

Subscribers implement event handling methods that will be called when an event is received.

@objc func onCountEvent(event: TPCountEvent, object: Any?) {
	// do something
}

Register and unregister your subscriber.

Notice: When the subscriber is released, it will be automatically unregistered.

// Register
 TPEventBus<TPCountEvent>.shared.register(eventType: TPCountEvent.self, subscriber: self, selector: #selector(onCountEvent(event:object:)))
 
 // Unregister
 TPEventBus<TPCountEvent>.shared.unregister(eventType: TPCountEvent.self, subscriber: self)

Post events:

 let event = TPCountEvent.init(count: count)
 TPEventBus.shared.post(event: event, object: self)

Convenience

TPEventBus<TPCountEvent>.shared.subscribe(eventType: TPCountEvent.self).onQueue(OperationQueue.main).onEvent { [weak self] (event, object) in
    guard let self = self else {
        return
    }
    
    // do something
}.disposed(by: self.tp_eventTokenBag)
