How to display the radius in MKCircle on Map in meters

I need to draw a circle of a radius 1.23 metre on MkMapView using MKCircle. How would i show that on the map. I used the following , 

  r = 1.23;// in metres.
  circle = [MKCircle circleWithCenterCoordinate:location radius:r];

But when i draw it on the map it looks like more than 1km on the MKMapView. Could someone please tell me how i could represent a circle of radius 1.23 metre on the map??

This is mainly to show the accuracy of the location, so the radius indicates the accuracy of the location.

iphone objective-c ios mkmapview

In the viewForOverlay delegate method, try setting the lineWidth of the MKCircleView to 1.

I think the default width of 0 results in the "road width".

MKCircle class definition says

radius

   The radius of the circle, measured in meters from the center point.

So your code should work fine.
