If you have fixed radius. Create image in photoshop. Assign it to marker. And set property as draggle to marker. So you will now be able to drag the marker as you want.

I investigated this for a few hours but no direct solution wasn't found so far. However, I found a way to achieve this. The solution is to clear circle and re-draw a new circle while dragging.

If a circle is drawn around a GMSMaker, dragging circle can be achieved to implement the delegate method that is called while dragging a marker:

 -(void)mapView:(GMSMapView *)mapView didDragMarker:(GMSMarker *)marker {
     [mapView clear];

     // Re-draw marker
     marker.map = mapView;

     // Create your circle with the new marker
     GMSCircle *circ = [GMSCircle circleWithPosition:marker.position radius:1000];
     circ.fillColor = [UIColor grayColor];
     circ.strokeColor = [UIColor redColor];
     circ.strokeWidth = 5;
     circ.map = mapView;
 }

EDIT:

Note that [mapView clear] clears all overlays (include makers). Sometimes it may not be a good solution.
