My goal is to load a KML file to display a layer on a SceneView using C# and Arcgis in both Windows and iOS.
The following code works in Windows XAML but it does not work on iOS.
// Create a new basemap.
Basemap imageryBasemap = Basemap.CreateImageryWithLabels();
// Create and show a new scene with imagery basemap.
MySceneView.Scene = new Scene(imageryBasemap);
KmlLayer layer;
layer = new KmlLayer(new Uri(name)); //name is a local filename
// Add the selected layer to the map.
MySceneView.Scene.OperationalLayers.Add(layer);
await layer.LoadAsync();
await MySceneView.SetViewpointAsync(new Viewpoint(layer.FullExtent));
This displays a KML layer at a specific location and zooms into it.
--------------------------------------------
Using iOS, the file has been included in the application package in a kml directory bundled with the application.
// Create a new basemap.
Basemap imageryBasemap = Basemap.CreateImageryWithLabels();
// Create and show a new scene with imagery basemap.
MySceneView.Scene = new Scene(imageryBasemap);
KmlLayer layer;
try
{
var uriname = new Uri("file:///./kml/mylayer.kml");
layer = new KmlLayer(uriname);
}
catch (Exception e)
{
Console.WriteLine("ERROR OPENING KML FILE: {0}", e.Message); // No error here.
return;
}
Console.WriteLine("KML FILE named {0} loaded...", layer.Name); // layer has no Name here which indicates to me that although the above didn't throw an exception the layer wasn't actually loaded.
// Add the selected layer to the map.
MySceneView.Scene.OperationalLayers.Add(layer);
// Zoomed into the approximate area but there is no layer shown on the map.
Envelope myEnvelope = new Envelope(-118.45, 45.92, -118.42, 45.95, SpatialReferences.Wgs84);
MySceneView.SetViewpointAsync(new Viewpoint(myEnvelope));
Any help is appreciated.
Also, any help to load a KmlLayer from a local data element or stream rather than from a URI would be great.
