For a discussion of how one goes about making non-ARC code enabled with ARC, I'd refer you to the Transitioning to ARC Release Notes . As Midhun alludes, you will be replacing retain references with strong references and eliminating release and autorelease . You'll also be removing calls to super dealloc .
So the conversion isn't hard, but there are a number of items to be conscious of.
When you convert it to ARC there will not be any.
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.
