I believe atomic synthesized properties already support this. The getter method retains and autoreleases the object before returning it to the caller, to ensure that it can’t be dealloced before the caller returns (or exits an @autoreleasepool block.) (Of course this adds a lot of overhead to the getter, which is why some people make all synthesized properties nonatomic unless they need to be thread-safe.) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
