I realize this is kind of an old question but maybe this will help someone else as well so here it goes: I think your best bet for this is to create an empty custom UIButton that overlays the image. You'll have to create a subclass of the TTTableitemcell you are using to do this if you haven't already.
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.
