Core Callbacks

Core callbacks as sent on core events, like on SDK Initialisation, User Identification, Event Tracking, Reward Received .

In order to integrate Core Callbacks follow these steps:

Add Callback Listener

Extend the class in which you want to Listen the Callback with NudgeGlobalCallback and register the class for receiving the callback by passing the instance of the class to NudgeGlobalCallbackManager's registerListener method. Now by overriding the onEvent method you can listen to the callbacks

public class YourClass: NudgeGlobalCallback {
     
    var callbackManager = NudgeGlobalCallbackManager.shared
    
    init() {
        callbackManager.registerListener(self)
    }
    
    public func onEvent(event: NudgeCallback) {
        switch event {
            case let coreEvent as NudgeCoreCallback:
                // Handle NudgeCoreCallback
                let action = coreEvent.action
                let data = coreEvent.data
            default:
                // Handle any other (perhaps unexpected) NudgeCallback subclasses
                break
        }
    }
}

Removing Listener

You must remove the callback listener, on the destory of the class.

callbackManager.unregisterListener(self)

Callback Name and Data
