If you have a pointer to the split view controller itself, you can do:

[(GeoDetailViewController *)[[(UINavigationController *)[[splitViewController viewControllers] objectAtIndex:1] viewControllers] objectAtIndex:0] populateDisplay:currentShape];

To get the pointer to your split view, you will probably have to go via your app delegate:

UISplitViewController *splitViewController = [(MyAppDelegate *)[[UIApplication sharedApplication] delegate] splitViewController];

(assuming that you are using the default split view controller template - YMMV depending on how you have implemented it)

Note that when you create your split view, you must set the detail view controller to be a GeoDetailViewController - if you are not and you cannot for app design reasons, I can edit my answer to work around that.
