Passing data from Marker to other VC

问题

At the beggining of this post I would like thank @Nirav D for help :)

Ok. So the problem.

There is a class i want to pass with prepareForSegue func with google marker. How to do it?

回答1:

You are too close to pass simply set the passedMarker with your array object.

if let marker = sender as? GMSMarker , //is it correct do declare marker as GMSMarker?
   let dict = marker.userData as? [String:Int] {

    let markerIndex = dict["index"]!
    nextVC.passedMarker = self.markers[markerIndex]
}

Now simply access passedMarker property in viewDidLoad of VC3.

Edit this performSegue(withIdentifier: "details", sender: marker)

To performSegue(withIdentifier: "details", sender: self)
