Pour appliquer un style de remplissage et de trait à un polygone de limite, utilisez une fermeture de style qui accepte un GMSPlaceFeature et renvoie un GMSFeatureStyle pour définir les attributs de style. Définissez ensuite la propriété de style sur une fermeture de style, qui contient la logique de style.
Swift
