SkechLayer load down tiled Map

[Promethia]

Hi
In my application i use different base map. When application is loaded for the first time, skechLayer draw up tiled map (OK), but when i change the base map the skechLayer draws down the tiled map.
i used this code:

AGSGraphicsLayer* graphicsLayer2 = [AGSGraphicsLayer graphicsLayer];
[self.mapView addMapLayer:graphicsLayer2 withName:@"Graphics Layer 2"];
self.sketchLayer = [AGSSketchGraphicsLayer graphicsLayer];
[self.mapView addMapLayer:self.sketchLayer withName:@"Sketch layer"];

Why?
Help me please

How you are changing the base map? You should use AGSMapView's insertMapLayer:withName:atIndex: method and insert base layer at index 0.

How you are chaining the base map? You should use AGSMapView's insertMapLayer:withName:atIndex: method and insert base layer at index 0.
