如何使用Google回调URL方案快速返回到您的应用程序？

Question

I am using the Gooogle Url Scheme to show the directions with the press of a button in swift. How can i use the url callback scheme to get back to my app, after i have opened the native google maps app. I am using the below code

if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"comgooglemaps://")!)) {
            UIApplication.sharedApplication().openURL(NSURL(string:
                "comgooglemaps://?saddr=&daddr=\(place.latitude),\(place.longitude)&directionsmode=driving")!)

        } else {
            NSLog("Can't use comgooglemaps://");
        }
    }

I have tried referring to this link Google Map Url Scheme if anyone knows how to do it, pls answer with a sample swift code

Answer 1

You can use the OpenInGoogleMaps component provided by Google Maps. It even lets you encode a redirect URL to your App, which is displayed on top of the directions in the Google Maps application.

This is what the code looks like in Swift:

var place: CLLocationCoordinate2D

var definition = GoogleDirectionsDefinition()
definition.destinationPoint = GoogleDirectionsWaypoint(location: place)
definition.travelMode = GoogleMapsTravelMode.Driving

OpenInGoogleMapsController.sharedInstance().openDirections(definition)
