Is there a better way to remove objects from a set? Perhaps there is
a safe
iteration that allows objects to be removed? I supposed I could keep a
separate list of objects that need to be removed, and then remove them
afterwards, but that seems like a clunky solution.
How about something like this?
for (id obj in [theSet allObjects])
{
if (something)
{
[theSet removeObject: obj
}
}
