Your responsibility is to balance your memory-related actions - alloc, copy, new, retain - with a release.
It is not your responsibility to guess how Apple's classes work. The implementation for addSubview could retain your slider one time, or it could retain it many times. You have no way of knowing. You have to trust that whatever Apple's classes DO, they will also UNDO appropriately. Same for arrays, dictionaries, etc. The act of adding an object to an array, just like adding your slider to a view, does not involve alloc, copy, or new (unless you do it wrong), so it should not be released.
