User Location (iOS)

Zeigt den aktuellen Standort des Benutzers auf der Karte an.

MapSession erforderlich

Denken Sie daran, die MapSession in Ihre App zu integrieren. Die MapSession muss alle 10 Minuten aufgerufen werden, solange die Karte aktiv ist.

Info.plist

Fügen Sie Ihrer Info.plist den folgenden Schlüssel hinzu:

<key>NSLocationWhenInUseUsageDescription</key>
<string>We need your location to show it on the map.</string>
