Change GMSMapView default map background color in iOS

Question

The GMSMapView in iOS has a default background color of tan, or something like it.

I have a requirement to change that color to white. I've tried using a subclass of GMSTileLayer without success (or errors). I need to place custom map overlays with white backgrounds onto the map view. In areas without the overlays, the base map color needs to match (white).

Tried the following without any luck:

[mapView setBackgroundColor:[UIColor whiteColor]];

Can anyone offer suggestions, or point me to a resource (other than Google) that might help?

Thanks!

I think you can only change the mapType of your mapView, otherwise you have to use the GMSTIleLayer. Currently, you can not change the color of the mapView with the iOS SDK. – Twandatwang

Now you can change GMSMapStyle of you map (available with Google Maps SDK for iOS 2.1). Styling works only on the kGMSTypeNormal map type. I create my own style with https://mapstyle.withgoogle.com/ Hope, it will help you.

As of release 8.3.0 (release notes), it is possible to override the default map background color by using the backgroundColor property that can be set on the GMSMapViewOptions object.

The documentation for the backgroundColor property states

Specifies the background color of the map view, which displays whenever the map tiles are not fully loaded.

It could look like this:

let options = GMSMapViewOptions()
options.backgroundColor = .red
let mapView = GMSMapView(options: options)

Is there any way of changing this after the map was initialized? Apparently if you give it a UIColor which supports both light/dark mode it only uses the theme it was initialized with. So you're stuck with only one color, even after user changed theme. – Motheaten
