title: Setting a property on a custom object through Interface Builder
body: <p>I have a custom UITableViewController subclass which I use in two places in a nib file. What should I do if I want the two instances to have slightly different behavior? Of course in the code I can select one kind of behavior or the other based on the value of a BOOL, but how do I set that BOOL from Interface Builder, without having to write an Interface Builder plugin?</p>
