Min Max Scale

Demonstrates how to set the minimum and maximum scale of an ArcGISMap.

How it works

To set the min and max scales on a ArcGISMap:

  1. Create an ArcGIS map.
  2. Set min and max scales of map, ArcGISMap.setMaxScale() and ArcGISMap.setMinScale().
  3. Set the ArcGIS map to theMapView.
