App crashes but only when it's build for Ad-Hoc distro?

It's hard to say exactly what the answer is without knowing more, but my first guess is that you are providing some invalid value to a UIView 's center property.

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.
