I think you meant the ‘atomic' property modifier. Note that the iOS team did not agree with Ali on this, due to the ginormous performance penalties in both CPU and memory: they made ‘nonatomic’ the standard for iOS, despite the fact that the language defaults to ‘atomic' and you therefore have to type ‘nonatomic' every time. Now considering the relative installed bases... Marcel p.s.: If I understand it correctly, ARC’s magic un-autoreleaser largely ameliorates the perf. problems _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
