title: Cannot pass message (or Call a function) using the outlet of a customized class
body: <p>When a class is customized, by using its outlet , you cant access its method. Is there any better solution to access the method of a customized class? without posting notification?</p>
  
  <p>To be more specific, sometimes when a Controller Class having outlets of other classes, could 
  access the method of the corresponding classes. But the reverse is not always true. Why is this behavior?</p>
