Delegate veeryPredictionUpdate

func veeryPredictionUpdate(_ veery : Veery, Predictions : Veery.Predictions)

Delegate Callback triggered when the backend computed a new prediction. You should implement VeeryDelegate in your ViewController to use it.

Your are warned only if you are called the requestPredictionUpdate and the activate(service : Int) with a service that include Veery.PREDICTION.

This could be used to refresh a Maps.

Parameters

Param name	Type	Usage
veery	Veery	none
Predictions	Veery.Predictions	a Predictions object

Returns

Void

Usage / Example

import Foundation
import UIKit
import Veery

class ViewController: UIViewController, VeeryDelegate {// Implement Veery Delegate

    // TODO : Inside the principal class (!!not inside a function)
    let veery = Veery()

     override func viewDidLoad() {
        super.viewDidLoad()
        // TODO : Init the delegate
        veery.delegate = self
        // TODO : declare your API Key Secret
        veery.setApiKeySecret("SuPeRScrET12345789GhJ")

        // TODO : Activate the required function levels (user will be requested to accept geolocation)
                    //
                    veery.activate(service: Veery.GEOPROFILE)
                    // Requires ios Veery 1.3.3
                    //veery.activate(service:Veery.BACKGROUND_GEOLOC | Veery.PREDICTION)


        veery.requestPredictionUpdate()
    }

    func veeryPredictionUpdate(_ veery: Veery, Predictions: Veery.Predictions) {

        if (Predictions?.isOk())! && ((Predictions?.getProbability())! > 0.5 ) {

        //.......
        //.......
        }
     }

    @IBAction func stopPrediction(_ sender: Any) {
         veery.stopPredictionUpdate()
    }
