Not in this code you don’t, unless you have a “automaticallyNotifiesObserversOfVersion” method returning false elsewhere in the class. The notification doesn’t happen in the synthesized implementation of the setter, but via a swizzled replacement setter that is normally installed only when something starts observing the property.

You do it in the “obvious” way — you declare a second, private property without a custom getter or setter, and you use this private property where you would have used the instance variable in Obj-C. The effect is the same, because the private property is optimized into just an instance variable, and the public property has no instance storage of its own (but you will have to provide a custom getter, too). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
