如何在bing地图上获取搜索地址的边界？

Question

我正在使用地址名称搜索位置，并使用坐标获取此地址在 bing 地图上的位置。

但这只显示搜索位置的图钉。

但我的要求是在必应地图上获得搜索地址的完整边界。

我正在使用下面的代码

`

extension ViewController: GeocodeAlertDelegate {

func searchButtonTapped(query: String, culture: String, region: String, useLocation: Bool, useBoundingBox: Bool) {
    guard !query.isEmpty else {
        return
    }

    var referenceLocation: MSGeopoint?
    if useLocation {
        referenceLocation = self.mapView.mapCenter
    }
    var referenceBoundingBox: MSGeoboundingBox?
    if useBoundingBox {
        referenceBoundingBox = self.mapView.mapBounds
    }

    let options = MSMapLocationOptions()
    if !culture.isEmpty {
        options.setCulture(culture)
    }
    if !region.isEmpty {
        options.setRegion(region)
    }

    MSMapLocationFinder.findLocations(query, withReferencePoint: referenceLocation, withReferenceBoundingBox: referenceBoundingBox, with: options, handleResultWith: { (result: MSMapLocationFinderResult) in
        switch result.status {
        case MSMapLocationFinderStatus.success:
            self.pinLayer.elements.clear()
            let locations = NSMutableArray()

            for mapLocation in result.locations {
                let pinLocation = MSGeopoint(
                    latitude: mapLocation.point.position.latitude,
                    longitude: mapLocation.point.position.longitude,
                    altitude: 0,
                    altitudeReferenceSystem: MSMapAltitudeReferenceSystem.terrain)
                print("AddressName:- \(mapLocation.address)")
                print("DisplayName:- \(mapLocation.displayName)")

                self.addPin(atLocation: pinLocation, withTitle: mapLocation.displayName)
                locations.add(mapLocation.point)
            }
            
            if locations.count > 1 {
                self.mapView.setScene(MSMapScene(locations: locations as! [MSGeopoint]), with: MSMapAnimationKind.default)
            } else {
                self.mapView.setScene(MSMapScene(location: locations[0] as! MSGeopoint), with: MSMapAnimationKind.default)
            }
        case MSMapLocationFinderStatus.emptyResponse:
            self.showMessage("No result was found")
        default:
            self.showMessage("Error processing the request")
        }
    })
}
}
