I've noticed that some of Apple's examples include both a retain and readonly modifier on properties. What's the point of including retain if no setter gets generated when we're using the readonly modifier? Example: @property (retain, readonly) NSString *title; from the AnimatedTableView sample.
Problems with NSSet (remove object and iterate)
Why does a declared property use both retain and readonly?
