Hmm, not exactly clear what you are trying to do but I will take a guess.

Yes, but it is generally better to use accessor methods; i.e. methods for
retrieving and setting the variables.

You can make an ObjC classes variables public, so that you can access them
as though it was a C structure.

@interface ToBeOwned
{
@public
  int x;
  int y;
}
@end

main()
{
  id anObj = [[ToBeOwned alloc] init];

  ((ToBeOwned *)anObj)->x = 5;
  ((ToBeOwned *)anObj)->y = 100;
}

Am I close to what you are looking for?
