Here's a simple Objective-C question with, I suspect, a simple yes-or-no  
answer.

Is it possible to access directly the values of variables in other objects?

  e.g., [anotherObject whatIsTheValueOf: this_variable];
  and   [anotherObject whatIsTheValueOf: that_variable];

It would be convenient not to have to dedicate a whole method to transferring  
the value of this_variable only; i.e., without putting

   - tellTheValueOfThisVariable:(float *)dummy_variable
   {
     *dummy_variable = this_variable;
   }

into the implementation of anotherObject.

Simply including the header file of the other object doesn't seem to do the  
trick.


Thanks in advance,

	The best way is to do it with the method returns value style.

	Otherwise, you aren't really working in a very Object Oriented way,  
plus you don't get the benefit of being able to change the variable type,  
without having to change anything in the objects that actually use it.
