How to Get Static Image from Google Maps in iOS

How to get static image from google maps in iOS

the reply of @Ankit is right, but @Alexsander asked in Swift, so :

var staticMapUrl: String = "http://maps.google.com/maps/api/staticmap?markers=color:blue|\(self.staticData.latitude),\(self.staticData.longitude)&\("zoom=13&size=\(2 * Int(mapFrame.size.width))*\(2 * Int(mapFrame.size.height))")&sensor=true"
var mapUrl: NSURL = NSURL(string: staticMapUrl.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding))!
var image: UIImage = UIImage.imageWithData(NSData.dataWithContentsOfURL(mapUrl))
var mapImage: UIImageView = UIImageView(frame: mapFrame)

for swift 4

let staticMapUrl: String = "http://maps.google.com/maps/api/staticmap?markers=\(self.finalLatitude),\(self.finalLongitude)&\("zoom=15&size=\(2 * Int(imgViewMap.frame.size.width))x\(2 * Int(imgViewMap.frame.size.height))")&sensor=true"

let mapUrl: NSURL = NSURL(string: staticMapUrl)!
self.imgViewMap.sd_setImage(with: mapUrl as URL, placeholderImage: UIImage(named: "palceholder"))

How to get static image from google maps in iOS in swift 3

Swift 3

        let Width = 100
        let Height = 200

        let mapImageUrl = "https://maps.googleapis.com/maps/api/staticmap?center="
        let latlong = "18.495651759752, 73.809987567365"

        let mapUrl  = mapImageUrl + latlong

        let size = "&size=" +  "\(Int(Width))" + "x" +  "\(Int(Height))"
        let positionOnMap = "&markers=size:mid|color:red|" + latlong
        let staticImageUrl = mapUrl + size + positionOnMap

        if let urlStr : NSString = staticImageUrl.addingPercentEscapes(using:String.Encoding.utf8)! as NSString{
            // setImageFromURL 
       }

Load static google map into UIImageView?

Well I ended up finding a solution for this so I'll post it in case someone else runs into the same issue.

First I changed the way I load the image to using NSURLConnection. I don't think this particular change makes a difference but this is what allowed me to find the problem. When trying to load the URL I got a "bad url" error. So I did some searching on that and turns out there are some invalid characters in the google static map URL that must be escaped.

So basically just call this on the url and you should be good to go:

// The URL you want to load (snipped for readability)
NSString *mapurl = @"http://maps.google.com/maps/api/staticmap?[...]";  

// Escape the string
mapurl = [mapurl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

I haven't tested this solution with the code I have in my original post but I did test it with my new NSURLConnection implementation and it works perfectly. I assume it'll work fine with the code above as well since it was just a matter of escaping the string.

not able to set map as image in uiimageview swift

Try this. Note you have to get API key from Google cloud

let API_Key = //Your API Key.
let url = "https://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=\(2 * Int(imgBanner.frame.size.width))x\(2 * Int(imgBanner.frame.size.height))&maptype=roadmap&key=\(API_Key)"
let mapUrl: NSURL = NSURL(string: staticMapUrl)!
self.imgBanner.sd_setImage(with: mapUrl as URL, placeholderImage: UIImage(named: "palceholder"))

Always check the link in browser to view whether it is working fine or not means the image is showing correctly without any Map error: g.co/staticmaperror. If you find any staticmaperror, please visit map-static-error-messages.

Sample image:

https://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=600x300&maptype=roadmap&key=AIzaSyAJgFSXOEIqBWIZ2vUcngjpX5fBBFmX6t0

Getting static image of Google Map

Static Maps may fit your use case: https://developers.google.com/maps/documentation/staticmaps/

But check the Terms of Use — both the usage limits (at that URL) and the Terms of Service 10.1.1(h).

Retrieve image from Google Maps in iOS

http://maps.googleapis.com/maps/api/staticmap?size=200x200&maptype=roadmap%%5C&markers=size:mid%%257Ccolor:red%%7CNew+York&sensor=false

Just needed to edit some of the % \ etc to incorporate the UTF8 encoding, however if you use the encoding method karthika suggested, it breaks the search. All I did was hard code the string and removed the added encoding before the address and its working perfectly.

Google Static Maps for iOS

From an ip or from a device number of free request that can be made from google is 25000 request only per day after this you have to pay to google for it. So answer to your question is request from a particular ip is considered for calulating total requests.

Google static maps don´t load in iOS devices

Ran the code in your question and was able to replicate your problem. This is happening due to new restriction on using http connections instead of https on iOS. Just like I mentioned in my comment, replacing WWW with UnityWebRequest solved this problem.

Also, you are unnecessarily creating new textures each time with new Texture2D(1280, 1280, TextureFormat.RGB24, false); is executed. This should be done with Unity's UI Component RawImage. In this case, no unnecessary memory allocation.

All you have to do to the code in your question is to remove the WWW API and use UnityWebRequest. Also remove Renderer or Texture2D and use RawImage to display your map. Below is a simple test script I used to test this. It runs on the both Editor,iOS and possibly all other platforms.

public class Gpsconnect : MonoBehaviour
{
    public RawImage imageDisp;
    public float fixLat = 42.3627f;
    public float fixLon = -71.05686f;
    public int zoom = 4;
    public string key = "";
    public Vector3 iniRef;
    public Transform cam;
    private Camera mycam;
    private string url = "";

    //Update Map with the corresponding map images for the current location ============================================
    IEnumerator load()
    {
        yield return null;
        mycam = Camera.main;
        fixLat = ((360 / Mathf.PI) * Mathf.Atan(Mathf.Exp(0.00001567855943f * (cam.position.z - 3 * mycam.orthographicSize / 2 + iniRef.z)))) - 90;
        fixLon = (18000 * (cam.position.x + iniRef.x)) / 20037508.34f;

        //MAP ================================================================================
        //Build a valid Google Maps tile request for the current location 

        url = "https://maps.google.com/maps/api/staticmap?center=" + fixLat + "," + fixLon + "&zoom=" + zoom + "&scale=2&size=640x640&style=feature:all|element:geometry|hue:0x00fff0|lightness:0|gamma:0.21|visibility:on&style=feature:all|element:labels|visibility:off&style=feature:landscape.man_made|element:geometry|color:0x133f42|visibility:on&style=feature:landscape.natural|element:geometry.fill|visibility:on|hue:0x00ffd2|saturation:35|lightness:0|gamma:0.5&style=feature:poi|element:geometry.fill|lightness:0|gamma:0.6|visibility:on&style=feature:poi.park|element:geometry|visibility:on|saturation:0|color:0x2e9470&style=feature:road|element:geometry.fill|visibility:on|color:0x05111a&style=feature:road|element:geometry.stroke|visibility:off&style=feature:transit|element:geometry|visibility:off" + "&sensor=false&key=" + key;

        UnityWebRequest www = UnityWebRequest.GetTexture(url);
        yield return www.Send();
        Debug.Log("Done: ");

        if (www.isError)
        {
            Debug.Log("Error while downloading image: " + www.error);
        }
        else
        {
            imageDisp.texture = ((DownloadHandlerTexture)www.downloadHandler).texture;
        }
    }

    void Start()
    {
        StartCoroutine(load());
    }
}
