If you want to use runtime you can get the Ivar from whatever class navigationController is apart of by using this:

Ivar var =  class_getInstanceVariable(your class, "navController");

and then with that Ivar you call upon the instance of your class using this method to get the object navController points to

UINavigationController* controller = object_getIvar(instanceofyourclasswithnavcontroller, var)
