Note

Bing Maps SDK for Android and iOS retirement

Bing Maps SDK for Android and iOS is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2025. Enterprise account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps SDK for Android and iOS will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

The Bing Maps API provides events that allow your application to respond to user actions.

Examples

Map holding event

The following example shows how to add a pushpin when a user holds their finger on the map.

Swift

mapView.addUserIsHoldingHandler{ (point:CGPoint, location:MSGeopoint?) -> Bool in
    if (location != nil) {
        let pushpin = MSMapIcon()
        pushpin.location = location
        self.pinLayer.elements.add(pushpin)
        return true
    }
   return false
}

Map tapped event

The following example shows how to change a MapIcon image and z index of the containing layer when a pusphin is tapped.

Swift

First, add a Sequence extension for MSMapElementCollection.
Second, add the following methods and variables to UIViewController:

// Create two layers in ViewController
private var buildingsLayer: MSMapElementLayer!
private var cityParksLayer: MSMapElementLayer!

// Create and add pushpin to building locations in  building layer
func createCityBuildingsCollection() {
    buildingsLayer = MSMapElementLayer()
    let pushpin = MSMapIcon()
    pushpin.location = MSGeopoint(latitude: 47.603830, longitude: -122.329900)
    pushpin.title = "Seattle City Hall"
    buildingsLayer.elements.add(pushpin)
    let pushpin2 = MSMapIcon()
    pushpin2.location = MSGeopoint(latitude: 47.606709, longitude:  -122.332672)
    pushpin2.title = "Seattle Public Library"
    buildingsLayer.elements.add(pushpin2)
    let pushpin3 = MSMapIcon()
    pushpin3.location = MSGeopoint(latitude: 47.604100, longitude:  -122.329204)
    pushpin3.title = "Municipal Court of Seattle"
    buildingsLayer.elements.add(pushpin3)
}

// Create and add pusphin to city park locaiton in city parks layer
func createCityParksCollection() {
    cityParksLayer = MSMapElementLayer()
    let pushpin = MSMapIcon()
    pushpin.location = MSGeopoint(latitude: 47.608313, longitude: -122.331218)
    pushpin.title = "Freeway Park"
    cityParksLayer.elements.add(pushpin)
    let pushpin2 = MSMapIcon()
    pushpin2.location = MSGeopoint(latitude: 47.602029, longitude:  -122.333971)
    pushpin2.title = "Pioneer Square"
    cityParksLayer.elements.add(pushpin2)
    let pushpin3 = MSMapIcon()
    pushpin3.location = MSGeopoint(latitude: 47.601990, longitude:  -122.330681)
    pushpin3.title = "City Hall Park"
    cityParksLayer.elements.add(pushpin3)
    let pushpin4 = MSMapIcon()
    pushpin4.location = MSGeopoint(latitude: 47.600619, longitude:  -122.324957)
    pushpin4.title = "Kobe Terrace Park"
    cityParksLayer.elements.add(pushpin4)
}

// Change z index of layer and icon images
func selectLayer(selectedLayer: MSMapElementLayer) {
    var deselectedLayer: MSMapElementLayer
    if selectedLayer == buildingsLayer {
        deselectedLayer = cityParksLayer
    }
    else {
        deselectedLayer = buildingsLayer
    }

    deselectedLayer.zIndex = 0
    for element in deselectedLayer.elements {
        let mapIcon = element as! MSMapIcon
        mapIcon.image = MSMapImage(uiImage:UIImage(named: "selectedMappin")!)
    }

    selectedLayer.zIndex = 0
    for element in selectedLayer.elements {
        let mapIcon = element as! MSMapIcon
        mapIcon.image = MSMapImage(uiImage:UIImage(named: "defaultMappin")!)
    }
}

Finally add the buildings/parks layer to the map and implement the handler for a user tapped interaction.

override func viewDidLoad() {

    createCityBuildingsCollection();
    createCityParksCollection();
    mapView.layers.add(buildingsLayer)
    mapView.layers.add(cityParksLayer)
    mapView.addUserDidTapHandler { (point:CGPoint, location:MSGeopoint?) -> Bool in
        let tappedElements = self.mapView.findMapElements(atOffset: point)
        if tappedElements.isEmpty {
            return false
        }

        let mapIcon = tappedElements.first as? MSMapIcon
        if mapIcon == nil {
            return false
        }

        if self.buildingsLayer.elements.contains(where: tappedElements[0]) {
            self.selectLayer(selectedLayer: self.buildingsLayer)
        }
        else{
            self.selectLayer(selectedLayer: self.cityParksLayer)
        }
        return true
    }
}
