Want to add UInavigationBar rightBarButton like 'Now Playing' button of ipod, which doesnot disappears between view Transitions?

Since each UIViewController has its own navigation item (a set of views in the navigation bar), you have to add the same button in each view controller's -viewDidLoad method. If the same button is used everywhere in your app, it makes sense to create a subclass of UIViewController which does just that and reuse this subclass throughout your app.

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.
