Application crashes only when run on device with warning “Application 'xxxxxxx' exited abnormally with signal 11: Segmentation fault: 11?

The crash log gives you line numbers for about where it went bad; you can use NSLog for "printf debugging" to narrow it down. This blogger explains how to make NSLog useful when running on hardware: http://objcolumnist.com/2009/12/19/redirecting-nslog-to-a-log-file.

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.
