I can only guess by your code that downloadSave in called in a separate thread as you have an NSAutoReleasePool (not saying thats what your doing but its likely). NSURLConnection can only respond to the delegate methods in the main thread when it is initialised in the main thread.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
