TPEventBus

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

EventBus in 3 steps

1. Define events:

   class TPCountEvent: NSObject, TPEvent {
   	var count: Int
   
       init(count: Int) {
           self.count = count
       }
   }

2. 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)

3. 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)
