I’m basically trying to duplicate the behavior of the iPod app on the iPhone, where when you select a song, the music player view slides in, and the navigation bar transitions to a new color.

My app is set up as a tabbed based application, with UITabBarController and a nested UINavigationController in each tab. Inside each UINavigationController for each tab is a UITableView. When I select an item in the table, I’m using pushViewController to slide to the next view, and I’ve set hidesBottomBarWhenPushed in the next view controller in order to slide the tabs away. The behavior is very close to the iPod ‘Now Playing’ page, which is nearly perfect.

The final problem is that I’m unable to transition the color of the navigation bar, like how the navigation bar in the iPod app fades from blue to black. I’m able to force the color change after the new view appears (in viewWillAppear), but the change is abrupt and does not mimic the behavior of the iPod app, with a fade effect.

Does anyone know what I’m missing here? It seems like a very simple and common UI that I’ve seen in several applications, but there doesn’t appear to be an obvious way to do it.

  1. You can animate the status bar style change to create an effect that’s pretty close.

    - (void)viewWillAppear:(BOOL)animated {     [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:animated];     self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; }

    As you’ve noticed the navigation bar style changes immediately, but the animated change to the status bar still provides the overall appearance of a transition.
