Hi, I am new on ArcGIS iPhone platform. I have already developed a iPhone application, app was using MapKit framework for Overlays[Polylines and Polygons] drawing but due to some issues we are replacing Apple Maps SDK with ArcGIS IOS map. But I am getting few issues with ArcGIS IOS Maps.
1) I am trying to draw the Polygon Objects on ArcGIS map but its not appearing/drawing in correct shape and on correct location. On Apple map Polygons were drawing in Square shape but on ArcGIS iPhone Map polygons are showing as "Infinite Lines". [ I have attached the Output of ArcGIS Map and Apple Maps ]
