How to change the theme of Google map from Night mode to Standard mode on button click in swift

Need some help regarding the themes of the Google map sdk . I have used a JSON file name as style2.json for calling the night mode of google map . The theme is changing properly from standard to the night mode . The only issue is i want to reconvert the Night mode map to the standard Map theme with all my placemarkers. Plese find the attached code

do {
            // Set the map style by passing the URL of the local file.
            if let styleURL = Bundle.main.url(forResource: "style2", withExtension: "json") {
                self.myMapView.mapStyle = try GMSMapStyle(contentsOfFileURL: styleURL)
            } else {
                NSLog("Unable to find style.json")
        } catch {
            NSLog("One or more of the map styles failed to load. \(error)")

I have used this code for Button named Night Mode i have another button Day mode .What should i do to bring map to standard theme on clicking the day mode ..


  • You can find out what the standard/default mapStyle is by printing its value when night mode is not on.

    I did exactly that, and found that it's nil, so you just need to set it to nil:

    self.myMapView.mapStyle = nil

    You should probably save the night style into a property or something, so that you don't have to re-read the file every time you switch to night mode.
