The only possible reason in your case is that you had not connected your datasource and delegate properly. If you've connected already, but still getting problems, then just disconnect all the connections and connect them again. Here's a sample image....
I took your code and tried it. Works perfectly for me. I think you have written and connected perfectly for UISearchBar and searchDisplayController.

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.
