[newbie] Use of accessors versus direct access of ivars

Subject: [newbie] Use of accessors versus direct access of ivars
From: Stuart Malin <email@hidden>

I have a class with ivars for which there are accessors. I understand that the importance of using a setter method (or to use setValue:ForKey:) to set the ivar so that KVO operates. However, Is there a compelling reason to use, in the methods of a class, a getter method (or valueForKey:) versus directly accessing an ivar of the class?

I have re-read both the Key-Value Observing Programming Guide and Key- Value Coding Programming Guide, and have not derived guidance from them on this question. Perhaps I have missed something. _______________________________________________
