Aidez-moi s'il vous plaît.Supprimer l'annotation sur la carte virtuelle swift3
Premier travail sur un projet, avec iBeacon impliqué, ce qui crée Carte virtuelle de l'intérieur d'un magasin.
Je sais comment faire tomber des épingles, avec un MapKit, mais comment puis-je le faire, si je n'ai que des CGPoints sur View? J'ai réussi à égoutter UIImage (avec une image de broche), sur une vue. Mais quand je tourne ou pince, il ne reste pas sur les coordonnées que j'ai abandonnées. est ici un code:
import UIKit
