How do I set custom navigation bar(title + titleView) for all navigation controllers and view controller?

You could create a subclass of UIViewController MyViewControllerWithBackButtonAndLogo (you can come up with a better name) then implement viewDidLoad to set up the navigation item. Make all your view controllers inherit from this base class. Then just make sure the view controllers call super viewDidLoad in their own implementations.

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.
