Google Maps ambiguous use of a GMSMapViewType

Question

I just upgraded to Xcode 7.1. When I try to set the mapType of a GMSMapView I get the error Ambiguous use of 'kGMSTypeNormal', Ambiguous use of 'kGMSTypeTerrain', and Ambiguous use of 'kGMSTypeHybrid'.

@IBOutlet weak var mapView: GMSMapView!

func myfunc() {
      if let myMapType = NSUserDefaults.standardUserDefaults().stringForKey(SettingsTableViewController.History.MapType) {
            switch myMapType {
            case "kGMSTypeNormal":
                mapView.mapType = kGMSTypeNormal
            case "kGMSTypeTerrain":
                mapView.mapType = kGMSTypeTerrain
            case "kGMSTypeHybrid":
                mapView.mapType = kGMSTypeHybrid
            default: break
                mapView.mapType = kGMSTypeNormal
            }
        } else {
            mapView.mapType = kGMSTypeNormal
        }
}

Answer 1

I'm not sure why but putting "GoogleMaps." in front of all the kGMSTypes (i.e. GoogleMaps.kGMSTypeNormal) fixed the problem.

I suspect this happens because the enums are duplicated in some frameworks and when using GoogleMaps.kGMS... you are referencing the constant using its absolute and unmistakable identifier. Any way - this works. – Ihab

Answer 2

mapView.mapType = GMSMapViewType(rawValue: 1)!

• kGMSTypeNormal = 1
• kGMSTypeSatellite = 2
• kGMSTypeTerrain = 3
• kGMSTypeHybrid = 4
• kGMSTypeNone = 5

Answer 3

here is the updated version

import UIKit      
import GoogleMaps

class ViewController: UIViewController, GMSMapViewDelegate {
    var mapView: GMSMapView!

    override func viewDidLoad() {
        super.viewDidLoad()
        mapView = GMSMapView(frame: self.view.bounds)
        mapView.animate(toViewingAngle: 45)
        mapView.mapType = GMSMapViewType.satellite
        self.view = mapView


    }

In Swift 3 use as bellow:

.normal .hybrid .satellite .terrain

Answer 5

If you open GMSMapViewType, you will see it defined as enum. In your switch statement, you're comparing it with strings which is wrong. You should better compare them with integers.

kGMSTypeNormal = 1
kGMSTypeSatellite = 2
kGMSTypeTerrain = 3
kGMSTypeHybrid = 4
kGMSTypeNone = 5

Doing let myMapType = NSUserDefaults.standardUserDefaults().integerForKey(SettingsTableViewController.History.MapType) if myMapType == 1 { mapView.mapType = kGMSTypeNormal } still gives me the same error. In fact, i'm unable to define the mapType anywhere in the class as it just comes up as being ambiguous. – Demonology

let myMapType = NSUserDefaults.standardUserDefaults().integerForKey(SettingsTableViewController.‌​History.MapType). What value do you get on myMapType? – Solitary

It is an Int. Xcode complains about this at compile time. – Demonology

I don't see any problem with this: if myMapType == 1 { mapView.mapType = kGMSTypeNormal }. So you must check this let myMapType = NSUserDefaults.standardUserDefaults().integerForKey(SettingsTableViewController.‌​History.MapType) – Solitary

Answer 6

You need to use like this

mapView.mapType = GoogleMaps.kGMSTypeSatellite
