This happens because you are running in a thread. User threads don't share the main threads autorelease pool, so you need to create your own. Otherwise, objects like these will never get released, thus leaking.
At the time you run that line of code, no NSAutoreleasePool has been created on the current 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.
