Understanding memory management in ios?

This code is leaking myArray because you lose the reference to NSArray that you've allocated on the first line; you don't need to alloc here, because on the second line you're assigning a new value to myArray.

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.
