performSelectorOnMainThread

I'm trying to use (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait, and I don't understand how to receive the argument.

From the docs: "The method should not have a significant return value and should take a single argument of type id, or no arguments."

I can make it work when my method has no arguments, but I want to pass a dictionary with some data. When I add (id)arg or (id*)arg, I get an exception with "selector not recognized".

What's the proper way to do this, and how would I retrieve the dict once I got it? Would I cast the object as an NSDictionary?

A bit of a sample is probably all I need.

Thanks
