IOS Updating ViewController UILabel from another Class?

Well, start with changing these properties to (nonatomic, weak) . This is the more correct approach. And it is not good practice to update display from one your model classes in MVC pattern.

So your logic in + (void)updatedisplay doesn't make sense to me, I think it should be something like +(NSString *) getStringToDisplay with functionality implied in the func. Name and label's text is updated in vc code based on the received string.

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.
