Key-Value coding of Cocoa makes get/set operation to properties simple. Anyway documentation says it only recognized pre-defined naming patterns. I think Declared Property could be supported by this feature. Actually basic access of Declared Property is just same with Key-Value coding's search pattern. The problem is custom accessor. Because the custom accessors are stored as an attribute of the property, I think it's easily possible to support them in Key-Value coding. But I can't find mention about this.
What is the regular behavior when using Key-Value coding for the Declared Properties with custom accessors?
