In this case, [super close] and [self close] are the same thing.
Because you never overrode the -close method in your subclass, it
doesn't matter, but if you ever do decide to override -close in your
subclass, all the parts where you call [super close] will be broken.
I'm going to make a bold statement: You should only ever call [super
someMethod] from within an overridden someMethod implementation. I
believe this is true in all cases (because I can't at the moment
imagine a case where you'd do otherwise). Third party opinions are
welcome.
