Mixing ARC with non-ARC generates EXC_BAD_ACCESS. How to fix?

If you are converting your project to ARC, you should enable ARC on all your code. Xcode will give you errors in all the places where you're doing things like calling autorelease retain and release . Just build, fix errors, build, fix errors...repeat until it builds successfully.

For any third-party code you're using, you should disable ARC. For any third-party compiled libraries you're referencing, you should be able to use them normally.

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.
