would anybody care to comment on this piece of code?
It allows you to do "prev" or "next" once in the detail view of a uiviewcontroller.
So, if you have 4 uiviewcontrollers, you can navigate from #3 to #2 with previous or #3 to #4 with next. It works, but, my question is, is this the best way to implement this? or, is there a better way.
