View controller is drawing under my navigation bar after popping ttthumbsviewcontroller

I'm implementing the TTThumbsViewController from the Three20 project and things are finally starting to take shape. I push the TTThumbsViewController from the current view controller by just pushing it onto the current stack and animate the transition (common navigation controller push).

My problem is that when I pop the TThumbsViewController view controller, the navigation controller is stuck in a mode where its view controllers are drawn UNDER the navigation bar (which is now translucent).

Solution

  • You need to reconfigure the original style of the status bar, navigation bar & tool bar when your view reappears. You can do this by implementing viewWillAppear: in your view controller:

    - (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];

  UINavigationController* navController = self.navigationController;
  navController.navigationBar.barStyle = UIBarStyleDefault;
  navController.navigationBar.tintColor = [UIColor redColor];
  navController.toolbar.tintColor = [UIColor redColor];

  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
}
