NavigationBarとToolBarを上下に移動させつつ消したり出したり

「押したら上と下にひゅっと逃げて、押したらそこからひゅっと出てくるようにして」
「あー、直ぐ出来ます。多分」
「よろしく」

ということで

viewcontroller.m

- (void) showNavigationToolBar {
    UINavigationBar *navBar = self.navigationController.navigationBar;
    float animationDuration = 0.1;
    [self.navigationController setNavigationBarHidden:NO animated:NO];

そんな派手な事はしてないんだけど、あんまし検索しても出てこなかったので備忘録として記載。
