I see most of your statement are ready for leak, e. G in the viewDidUnload method , you are not releasing any instance member properly.
You have several places where you call XXX alloc init where XXX is a NSMutableArray or NSMutableString. You never release these and they are not autoreleased, thus they leak.
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.
