This feels like it should be a very basic question, but it's not one I've managed to find an answer to - can somebody here advise?
I have an objective c object which contains a number of properties that serve as parameters for an algorithm. They are bound to UI elements. I would like to take a snapshot copy of the object that will be used for one whole run of the algorithm (rather than risk parameters changing halfway through the run). i.e. I just want to do [myObject copy]. The complication is in ensuring this is threadsafe: ideally I would like to make the copy on a thread other than the main thread. My understanding is that properties themselves, even when designated atomic, are in some way not fully threadsafe, although I haven't found a clear explanation of exactly what makes them unsafe. I don't know if the 'copy' method is threadsafe or not, I am inclined to suspect not. Is there any way, then, that I can take a copy in a threadsafe manner? If necessary I can do the copy on the main thread, but I would prefer not to have to do that for timing reasons. Any suggestions?
