Thanks, this seems to work perfectly!
I recently read about shallow and deep copies, but didn't see the
initWithDictionary:copyItems: method.
Thanks,
Joe

I'm trying to create a private copy of an object, but yet when the

I have an array of dictionaries called spacesData. Then, when I do:
NSDictionary *backup = [[spacesData objectAtIndex:index] copy];
everything is fine, and this one looks as it should. Then, when I
change something in spacesData objectAtIndex:index], this private
copy changes too. Doesn't "copy" create a private copy, or am I
doing something wrong?
Copying a collection makes a shallow copy, so only the collection
itself is copied, not the values that it contains. If you want to
copy values, check out -[NSDictionary
initWithDictionary:copyItems:], or CFPropertyListCreateDeepCopy().
