didTapInfoWindowOfMarker on iOS App Swift

Question

Right now my app has multiple markers on different locations. If you tap on a marker, there is a small window popping out including a title and a snippet. I would like to implement a button in the window, or make the info window tappable, so it works as a button to execute a function. So I wrote this block in my GoogleMapsViewController.swift:

func mapView(mapView: GMSMapView, didTapInfoWindowOfMarker marker: GMSMarker) {

    print("test")
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier("jobDetailVC") as! JobDetailViewController

    if let value = marker.userData as? PFObject {
        vc.name = value.objectForKey("name") as? String
        vc.descriptionF = value.objectForKey("description") as? String
        vc.price = value.objectForKey("price") as? Double
        vc.objectId = value.objectId!
    }
}

The reason why I am using: didTapInfoWindowOfMarker is because I wasn't sure how to implement it, so I read the docu from Google Maps: https://developers.google.com/maps/documentation/ios-sdk/reference/protocol_g_m_s_map_view_delegate-p?hl=es and thought that this was the best choice.

Has anyone successfully implemented this, or something similar? Thanks in advance for the help!

You are right in using didTapInfoWindowOfMarker function to add an event in your InfoWindow.

When you're adding Map, add:

 mapView_.delegate=self;

Then use this to add the event/function of infoWindow when clicked:

-(void)mapView:(GMSMapView *)mapView
didTapInfoWindowOfMarker:(id<GMSMarker>)marker{

   //Info window function

}

Example on GitHub:

// when user tap the info window of store marker, show the product list
    func mapView(mapView: GMSMapView!, didTapInfoWindowOfMarker marker: GMSMarker!) {
        let storeMarker = marker as StoreMarker
        performSegueWithIdentifier("productMenu", sender: storeMarker.store)
    }

// when user tap the info window of store marker, pass selected store to the product list controller
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        let controller = segue.destinationViewController as ProductMenuController
        controller.store = sender as Store
    }

func mapView(mapView: GMSMapView, didTapInfoWindowOfMarker marker: GMSMarker) {

        for location in locations {
            let pollution = location[0]
            if pollution.locationdesc == marker.title {
                performSegueWithIdentifier(segueIdentifiers.locations, sender: location)
                break
            }
        }
    }
