Location Service on iOS
I'm building an App that displays a Google Static Maps of where the user is located. I've built on Android and it all works as expected, however, on iOS the latitude and longitude values don't change and the Google Static Map doesn't display.
The error I get when running in Xcode is:
Location service updates are not enabled. Check LocationService.status before querying last location.
In Xcode I have added all the Location related permission to the Info.plist and even added the MapKit.framework, but it doesn't fix the issue.
Has anyone else had this issue?
Here are my two scripts:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
public class GoogleMap : MonoBehaviour
{
public enum MapType
{
RoadMap,
Satellite,
Terrain,
Hybrid
}
public bool loadOnStart = true;
public bool autoLocateCenter = true;
public GoogleMapLocation centerLocation;
public int zoom = 13;
public MapType mapType;
public int size = 512;
public bool doubleResolution = false;
public GoogleMapMarker[] markers;
public GoogleMapMarker[] endMarkers;
public GoogleMapPath[] paths;
public GameObject radiusMarker;
public GameObject AugmentButton;
public Text ProximityText;
public float distanceFromTarget = 0.0003f;
private float proximity;
private Vector2 targetCoordinates;
public float dLatitude = 52.236955f, dLongitude = -0.901292f;
private float getLat;
private float getLong;
Vector2 RCurrentPos;
void Start() {
targetCoordinates = new Vector2(dLatitude, dLongitude);
}
public void Refresh() {
getLat = GPSscript.lat;
getLong = GPSscript.longi;
if (autoLocateCenter && (markers.Length == 0 && paths.Length == 0))
{
Debug.LogError("Auto Center will only work if paths or markers are used.");
}
StartCoroutine(_Refresh());
}
IEnumerator _Refresh()
{
var url = "https://maps.googleapis.com/maps/api/staticmap";
var qs = "";
if (!autoLocateCenter)
{
if (centerLocation.address != "")
qs += "center=" + WWW.UnEscapeURL(centerLocation.address);

}
qs += "&zoom=" + zoom.ToString();
}
qs += "&size=" + WWW.UnEscapeURL(string.Format("{0}x{0}", size));
qs += "&scale=" + (doubleResolution ? "2" : "1");

var usingSensor = false;
#if UNITY_IPHONE
usingSensor = Input.location.isEnabledByUser && Input.location.status == LocationServiceStatus.Running;
Debug.Log("iOS Stuff");
#endif
qs += "&sensor=" + (usingSensor ? "true" : "false");
foreach (var i in markers)
{

}
foreach (var i in endMarkers)

foreach (var loc in i.locations)
{
if (loc.address != "")
qs += "|" + WWW.UnEscapeURL(loc.address);
else
qs += "|" + WWW.UnEscapeURL(string.Format("{0},{1}", loc.latitude, loc.longitude));
SetLocation(getLat, getLong);
}
}
foreach (var i in paths)
{
qs += "&path=" + string.Format("weight:{0}|color:{1}", i.weight, i.color);
if (i.fill) qs += "|fillcolor:" + i.fillColor;
foreach (var loc in i.locations)
{

else
qs += "|" + WWW.UnEscapeURL(string.Format("{0},{1}", loc.latitude, loc.longitude));
}
}
var req = new WWW(url + "?" + qs);
yield return req;
GetComponent<Renderer>().material.mainTexture = req.texture;
}
void SetLocation(float latitude, float longitude)
{
RCurrentPos = new Vector2(latitude, longitude);
proximity = Vector2.Distance(targetCoordinates, RCurrentPos);
ProximityText.text = "Distance from destination: " + proximity;
if (proximity <= distanceFromTarget)
{
AugmentButton.SetActive(true);
radiusMarker.transform.position = new Vector3(0,1,6);
Debug.Log("It worked");
}else {
AugmentButton.SetActive(false);
radiusMarker.transform.position = new Vector3(0, -1, 6);
Debug.Log("Didnt work");
}
}
public enum GoogleMapColor

}
[System.Serializable]
public class GoogleMapLocation

public class GoogleMapPath
{
public int weight = 5;
public GoogleMapColor color;
public bool fill = false;
public GoogleMapColor fillColor;
public GoogleMapLocation[] locations;
}
}
And this one:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GPSscript : MonoBehaviour
{
private Vector2 targetCoordinates;
private Vector2 deviceCoordinates;
public static float lat;
public static float longi;
public GoogleMap mapScript;
public GameObject radius;
private bool ready = false;
private void Start()
{
StartCoroutine(StartLocationService());
StartCoroutine(updateGPS());
}
public IEnumerator StartLocationService(){
if (!Input.location.isEnabledByUser){
Debug.Log("User has not enabled GPS");
yield break;
}
Input.location.Start();
int maxWait = 20;
while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
{
yield return new WaitForSeconds(1);
maxWait--;
}
if (maxWait < 1)
{
Debug.Log("Timed out");
yield break;
}
if (Input.location.status == LocationServiceStatus.Failed)
{
Debug.Log("Unable to determine device location");
yield break;
}
else
{
longi = Input.location.lastData.longitude;
lat = Input.location.lastData.latitude;
}
ready = true;
}
public IEnumerator updateGPS()
{
float UPDATE_TIME = 1f;
WaitForSeconds updateTime = new WaitForSeconds(UPDATE_TIME);
while (true)
{
mapScript.Refresh();
longi = Input.location.lastData.longitude;
lat = Input.location.lastData.latitude;
SetLocation();
yield return updateTime;
}
}
void SetLocation()
{
radius.transform.position = new Vector3(0, 0, 6);
}
}
Did you @hollym16 or anyone manage to get this script to work?
