How to get a return value from a function which is called through NSthread?

Answer 1

The "return value" shouldn't be returned by the method, but it should update a class iVar and notify whoever was waiting for the object that it is now ready (by notify I don't necessarily mean NSNotificationCenter). Good luck.
