Class extensions are also the one place where you can redeclare that a property is readwrite.
Hi! Bill makes a very well-written explanation, but I beg to append (in a very nit-picky fashion) to this point, if only for the sake of the archives. If one visits <http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Articles/chapter_5_section_3.html >, one sees (under "Property Re-declaration") that:
If you declare a property in one class as readonly, you can redeclare it as readwrite in a class extension (see “Extensions”), a protocol, or a subclass
Cheers,
