A problem I see with this code is that you only set the cell contents when you create a new cell, i.e. Inside if (cell == nil) and not when you reuse an already existing cell via dequeueReusableCellWithIdentifier . So, in this case you get a cell with old contents and you don't set the "right" contents.
I suggest moving some statements out of the if block.
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.
