Code to use MAUI (until official support in ArcGIS Runtime for .NET)

esp1rl — Sat, 26 Mar 2022 21:11:44 GMT

Tested with MAUI Preview 14 and ArcGIS Runtime for .NET 100.13

Works on Windows and Android, but not IOS.

Code to create a MapView control for use in MAUI, and map it to the ArcGIS Runtime MapView.

using Microsoft.Maui.Handlers; using EsriMap = Esri.ArcGISRuntime.Mapping.Map; namespace MauiApp; public interface IMapView : IView { EsriMap Map { get; set; } } public class MapView : View, IMapView { public static readonly BindableProperty MapProperty = BindableProperty.Create( nameof(Map), typeof(EsriMap), typeof(MapView)); public EsriMap Map { get => (EsriMap)GetValue(MapProperty); set => SetValue(MapProperty, value); } } public class MapViewHandler : ViewHandler<IMapView, Esri.ArcGISRuntime.UI.Controls.MapView> { public MapViewHandler() : base(PropertyMapper, CommandMapper) { } public static readonly PropertyMapper<IMapView, MapViewHandler> PropertyMapper = new PropertyMapper<IMapView, MapViewHandler>(ViewMapper) { [nameof(IMapView.Map)] = MapMap }; public static readonly CommandMapper<IButton, IButtonHandler> CommandMapper = new CommandMapper<IButton, IButtonHandler>(ViewCommandMapper); private static void MapMap(MapViewHandler handler, IMapView view) { handler.PlatformView.Map = view.Map; } protected override Esri.ArcGISRuntime.UI.Controls.MapView CreatePlatformView() { #if ANDROID return new Esri.ArcGISRuntime.UI.Controls.MapView(Context); #else return new Esri.ArcGISRuntime.UI.Controls.MapView(); #endif } }

ConfigureMauiHandlers(handlers => { handlers.AddHandler(typeof(MapView), typeof(MapViewHandler)); });

Add ArcGIS Runtime NuGet packages.

.NET 6-ios and .NET 6-android support isn't at this point supported, but considered preview. After we shipped Update 13, Microsoft updated their .NET 6 ios runtime with lots of breaking changes, which is what you're hitting.

We just shipped Update 13.1 a few days ago, and it's compiled with the latest, so (for now at least) that version should work with iOS (I've successfully used it). I have a MAUI sample here you can also play with and is quite similar to what you have: https://github.com/dotMorten/MauiPlayground/tree/main/Esri.ArcGISRuntime.Maui

Thanks Morten, I will update to v13.1 and get IOS up and running.

Good news! We have an official preview you can now use: https://community.esri.com/t5/arcgis-runtime-sdks-blog/announcing-preview-1-of-net-maui-support-with/ba-p/1160505

Hi Morten,

Wondering if anything in the latest updates might impact iOS showing a MapView. I'm at Visual Studio Version 17.3.0 Preview 3.0 and Runtime 100.14.1-preview3. I get a map to show up in Windows but not in iOS 15.5 simulator.

Thanks -Joe

There's a known issue with the ios simulator in 14.1. Please see the workaround I put here: https://community.esri.com/t5/arcgis-runtime-sdk-for-net-questions/ios-emulator-with-arcgisruntime-maui-crashes/m-p/1190434/thread-id/11124
