'Open map URL' sample with a custom implementation of the OnMapsClicked method crashes and returns the error message, "Exception Unhandled System.ObjectDisposedException: 'Cannot access a disposed object. Object name: 'MapView'.'" after locking and unlocking the device.

Use a custom renderer for MapView. Refer to: https://community.esri.com/t5/arcgis-runtime-sdk-for-net/mapview-objectdisposedexception-ios/m-p/668849#M8426. 

[assembly: ExportRenderer(typeof(Esri.ArcGISRuntime.Xamarin.Forms.MapView), typeof(MyMapViewRenderer))]

namespace xxx.Forms.iOS

{

public class MyMapViewRenderer : MapViewRenderer 

{

protected override bool ManageNativeControlLifetime => false;

}

}
