Program received signal: “EXC_BAD_ACCESS?

If you have objective-c objects as plain structure fields then they are not initialized by default and so in your code you're trying to send message to uninitialized object and thus get EXC_BAD_ACCESS error.

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.
