I currently have a property declared as follows: @property(atomic, readwrite, retain) MyFrame* latestFrame;
When the value is set, I would like to broadcast a notification on the main thread, and one way of doing that would be to write my own custom setter that sets the value and then broadcasts the notification. What I am not sure about is how much I need to do to ensure this is threadsafe. I have only been able to find limited, rather contradictory information on this. When I write my own setter function, does the "atomic" qualifier have any meaning? What I am trying to work out is whether the runtime will bracket my function with appropriate locking code, or whether I need to do that myself - and so crucially, do I ALSO need to write a custom getter function that is subject to the same manual locking? [I have since wondered whether actually the "right" way of achieving what I want is to implement a didChangeValueForKey method from which I do the broadcasting. Any comments on that approach would also be welcome!] Thanks in advance Jonny_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
