Answer 1

This will show the navbar on the second screen:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];        
    self.navigationController.navigationBarHidden = NO;
}

You will also need to hide the navbar when you return to the first screen:

- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];        
    self.navigationController.navigationBarHidden = YES;
}
