Show GMSPolyline Title On Tap

I'm using Google Maps SDK for an iOS application of mine.

I configured it so that when a tap occurs on a

GMSMarker
, it shows it's title. It's working alright.

I want to do the same for
GMSPolyline
s but couldn't figure out how. The lines's
tappable
property is set to
true
.

How can I achieve this. Thanks.

P.S. coding with Swift 2.0

Answer

Conform to the protocol GMSMapViewDelegate:

class ViewController: UIViewController, GMSMapViewDelegate {
  ...
}

Set the ViewController to be the delegate of your map view:

override func viewDidLoad() {
  ...
  viewMap.delegate = self
}

Use the method mapView:didTapOverlay:

func mapView(mapView: GMSMapView, didTapOverlay overlay: GMSOverlay) {
  print(overlay.title)
}

This method is called whenever a tap is detected inside the map view.
