No. "Send the release message to the property" is a meaningless phrase. Only objects can receive release messages, and the property accessor returns the same address that is stored in the ivar, so the same object would receive the -release message. Also, property accessors are only called with either dot or method syntax; plain old `myFoo = bar` will not call -setFoo:. > Apparently, self->myFoo is capable of reaching the synthesised ivar. Alexander is correct that plain old `myFoo` will also access the synthesized ivar. There used to be a GCC bug in which synthesized ivars were inaccessible (at least through self-> syntax; now I can't recall whether they were wholly inaccessible). That, combined with the fact that there is no declaration of the ivar in scope, has led me to always use self-> syntax. I can't even recall seeing it documented that @synthesize myFoo; puts the myFoo symbol in scope; if it has ever been documented, I can't find it now. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
