let toolbar = FUIMapToolbar(mapView: mapView)
let legend = FUIMapLegend()
legend.toolbarButton = FUIMapToolbarLegendButton()
legend.headerTextView.text = "MapView Example Legend"
legend.passThroughViews = [toolbar, mapView]

var venueItem = FUIMapLegendItem(title: "Self Service")
venueItem.backgroundColor = UIColor.preferredFioriColor(forStyle: .map1)
let venueImage = FUIAttributedImage(image: FUIIconLibrary.map.marker.venue.withRenderingMode(.alwaysTemplate))
venueImage.tintColor = .white
venueItem.icon = FUIMapLegendIcon(glyphImage: venueImage)

var valetItem = FUIMapLegendItem(title: "Valet")
valetItem.backgroundColor = UIColor.preferredFioriColor(forStyle: .map2)
let valetImage =  FUIAttributedImage(image: FUIIconLibrary.map.marker.walk.withRenderingMode(.alwaysTemplate))
valetImage.tintColor = .white
valetItem.icon = FUIMapLegendIcon(glyphImage: valetImage)
valetItem.line = FUIMapLegendLine(dashPattern: [10,8], dashPhase: 3.0)

let highActivityRegion = FUIMapLegendFillItem()
highActivityRegion.fillColor = UIColor.preferredFioriColor(forStyle: .map3)
highActivityRegion.borderColor = UIColor.preferredFioriColor(forStyle: .map3)
var highActivityRegionItem = FUIMapLegendItem(title: "High Activity Region")
highActivityRegionItem.fillItem = highActivityRegion

var highTrafficPathItem = FUIMapLegendItem(title: "High Traffic Path")
highTrafficPathItem.backgroundColor = UIColor.preferredFioriColor(forStyle: .map4)
highTrafficPathItem.line = FUIMapLegendLine(dashPattern: [2,2], dashPhase: 0.0)

legend.items = [highActivityRegionItem, valetItem, venueItem, highTrafficPathItem]

let legendHandler: ((FUIButton) -> Void)? = { [weak self] button in
    DispatchQueue.main.async {

        var dismissLegendAndRestoreCachedController = { [unowned self, unowned button] in
           self.dismiss(animated: true, completion: {
           button.isSelected = false
           })
        }

        let presentNewLegendPhone = {
           self.present(legend, animated: true, completion: nil)
        }

        let presentNewLegendPad = {
           legend.setupPopoverAttributes(popOver: legend.popoverPresentationController!, sender: button)

           dismissLegendAndRestoreCachedController()
           return
        }

        let presentNewClosure = UIDevice.current.userInterfaceIdiom == .phone ? presentNewLegendPhone : presentNewLegendPad

        guard let presentedController = UIDevice.current.userInterfaceIdiom == .phone ? self.presentedViewController : self.popoverPresentationController?.presentedViewController else {
           presentNewClosure()
           return
        }
