Location Details for iOS

Last updated:

  1. Developing on the new Arm-based Apple Silicon (M1) Macs requires building and running on a physical iOS device or using an iOS simulator running iOS 13.7, e.g. iPhone 11. This is a temporary limitation in Google Maps SDK for iOS, and as such also a limitation in MapsIndoors, due to the dependency to Google Maps.
  2. Note: Due to a bug in CocoaPods it is necessary to include the post_install hook in your Podfile described in the PodFile post_install wiki.

This is an example of displaying some details of a MapsIndoors location

Start by creating a UIViewController class that conforms to the GMSMapViewDelegate protocol

class LocationDetailsController: UIViewController, GMSMapViewDelegate {

Add a GMSMapView and a MPMapControl to the class

var map: GMSMapView? = nil
var mapControl: MPMapControl? = nil

Add other views needed for this example

var detailsView:UIStackView = UIStackView.init()
var mainView:UIStackView = UIStackView.init()
var nameLabel = UILabel.init()
var descrLabel = UILabel.init()

Inside viewDidLoad, setup the map and the mapControl instance:

self.map = GMSMapView.init(frame: CGRect.zero)
self.map?.delegate = self
self.map?.camera = .camera(withLatitude: 57.057964, longitude: 9.9504112, zoom: 20)
self.mapControl = MPMapControl.init(map: self.map!)

Setup the label views

nameLabel = UILabel.init()
descrLabel = UILabel.init()
nameLabel.backgroundColor = UIColor.white
descrLabel.backgroundColor = UIColor.white

Arrange the labels inside a stackview

detailsView = UIStackView.init(arrangedSubviews: [nameLabel, descrLabel])
detailsView.axis = .vertical

Arrange the map and the stackview inside another stackview

mainView = UIStackView.init(arrangedSubviews: [map!, detailsView])
mainView.axis = .vertical

When marker is tapped, get related MapsIndoors location object and set label text, based on the name and description of the location

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
let location = mapControl?.getLocation(marker)
if location != nil {
self.nameLabel.text = location?.name
self.descrLabel.text = location?.descr
}
return false
}

When map is tapped, reset label text

func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
self.nameLabel.text = nil
self.descrLabel.text = nil
}

See the sample in LocationDetailsController.swift
