Google Maps iOS SDK, Obtenir les itinéraires entre 2 lieux

Pendant que j'utilise Google Maps SDK, j'essaie d'obtenir le sens de la conduite entre deux emplacements sur iOS. Je sais que nous pouvons le faire en utilisant deux méthodes: -

1.) Utilisation du schéma d'URL pour lequel il est nécessaire que Google Maps App soit installé sur votre appareil.

2.) À l'aide de l'API Directions, via Request-Response, puis en analysant le JSON. Afficher des marqueurs pour montrer la direction.

Maintenant, ma question est-il un autre moyen par lequel je peux le faire sur iOS? J'ai besoin d'indiquer la direction de mon emplacement actuel à un emplacement particulier dont je dispose le Lat/Long.

Je veux dire est-il vraiment pas possible de simplement passer 2 emplacement comme paramètre et Google Maps SDK, va me donner les instructions?

Merci,

On dirait que vous recherchez une interface utilisateur Chrome, comme l’application Google Maps l’affiche. Google Maps SDK pour iOS vous peindra une carte, mais vous êtes responsable du chrome supplémentaire de navigation.

Vous pouvez utiliser le Google Directions API pour demander des directions, puis utiliser le chemin codé renvoyé par le service pour dessiner une méthode GMSPolyline en utilisant le chemin pathFromEncodedPath de GMSPath: .

Remarque: assurez-vous que le lecteur de DVD de votre API Google Direction est activé dans votre console de développeur Google.

Ces lignes indiquent l’emplacement entre une latitude/longitude donnée et l’emplacement de l’utilisateur;

NSString *googleMapUrlString = [NSString stringWithFormat:@"http://maps.google.com/?saddr=%f,%f&daddr=%@,%@", mapView.userLocation.coordinate.latitude, mapView.userLocation.coordinate.longitude, destinationLatitude, destinationLongtitude];
