You'd use viewDidUnload to release view objects. In this case, you'd want to release them in didReceiveMemoryWarning, and if they are ivars (they probably are; otherwise you wouldn't have a reference to release them with), you should also release them in dealloc.
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.
