1. Create MyParameters instance on some object on the main thread and call
it mainParameters for example.
2. All values are UI related, so, fill them on the main thread. But lock
your mainParameters object before. So, on the main thread do this ...
@synchronized( myObjectHoldingMyParameters.mainParameters ) {
myObjectHoldingMyParameters.mainParameters.X = X;
...
}
3. When you do want a copy on any other thread, do this ...
MyParamaters *paramsCopy;
@synchronized( myObjectHoldingMyParameters.mainParameters ) {
paramsCopy = [myObjectHoldingMyParameters.mainParameters copy];
}
... and implement deep copy without locking. It's done via @synchronized.
