Google Maps iOS Reverse Geocoding

Question

I am having an issue with Google Maps Reverse Geocoding when it comes to setting a UILabel\'s text to the reverse geocoded address. The UILabel is in an XIB use as a custom info

Answer 1

You are using a return out of the braces of the geocoding, for this reason the last code works. You should do something like this:

func getAddress(currentAdd : ( returnAddress :String)->Void){

    let infoWindow = NSBundle.mainBundle().loadNibNamed("InfoWindowCurrent", owner: self, options: nil)[0] as! InfoWindowCurrent
    let geocoder = GMSGeocoder()
    let coordinate = CLLocationCoordinate2DMake(Double(self.locLatitude)!,Double(self.locLongitude)!)


    var currentAddress = String()

    geocoder.reverseGeocodeCoordinate(coordinate) { response , error in
        if let address = response?.firstResult() {
            let lines = address.lines! as [String]

            currentAddress = lines.joinWithSeparator("\n")

            currentAdd(returnAddress: currentAddress)
        }
    }     
}

And call that function

  getAddress() { (returnAddress) in      

    print("\(returnAddress)")

    }

The first response worked for me. As an alternative to

marker.title = lines.joined(separator: "\n")`

try this, it will give you the street address:

marker.title = response?.firstResult()?.thoroughfare
marker.snippet = response?.firstResult()?.locality

For the city, try

marker.snippet = response?.firstResult()?.locality

So, I ended up going another route. It's not pretty, but it works. Each GMSMarker has a "userData" attribute that can be used to pass data. What I did was moved the marker creation into the reverse geocode completion handler and assigned the address to the "userData" attribute. Then, when the user taps to show the current address, the reverse geocode is kicked off, the marker is created and placed on the map.

geocoder.reverseGeocodeCoordinate(position) { response, error in
    if let location = response?.firstResult() {
        let marker = GMSMarker(position: position)
        let lines = location.lines! as [String]

        marker.userData = lines.joined(separator: "\n")
        marker.title = lines.joined(separator: "\n")
        marker.infoWindowAnchor = CGPoint(x: 0.5, y: -0.25)
        marker.accessibilityLabel = "current"
        marker.map = self.mapView

        self.mapView.animate(toLocation: position)
        self.mapView.selectedMarker = marker
    }
}

And when the marker is selected, the label is set to the address as passed in the "userData" attribute:

let infoWindow = Bundle.main.loadNibNamed("InfoWindowCurrent", owner: self, options: nil)?[0] as! InfoWindowCurrent

infoWindow.labelAddress.text = marker.userData as? String

return infoWindow
