Answer 1

You could hide the navigation bar:

- (void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[self navigationController] setNavigationBarHidden:YES animated:NO];
}

Answer 2

Modal view? -presentModalViewController:animated:, you can set the style (slide up, flip, dissolve, page curl) with the modalTransitionStyle property (on the view controller to become modal)
