I betcha this is the problem line. Unless you are writing a file to that location elsewhere in code, there is no file at localFilePathTemp . Since that file is empty, your initWithContentsOfFile returns a nil dictionary, and the rest is a chain reaction of nil objects.
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.
