IMHO it is never a bad idea to manage an objects life time using
proper retain/release semantics, you shouldn't care that it is a
singleton, you should treat it just as any other object. I say this
because it is possible that at some point in the future it may no
longer be a singleton (granted for ones documented by Apple to be a
singleton you could make such assumptions but still I think you should
treat it like any other object).
In my own code when I write or use a singleton (app-life long
singleton) of my own creation I always treat it as an object that I
need to manage the life time of. I even implement and maintain a
proper dealloc method in the singleton. This allows me the freedom
change it away from being a singleton in the future in the need
arises.
