Answer 1

You have to use set the hidesBottomBarWhenPushed property to YES on the controller that you are pushing and NOT to the UITabBarController.

otherController.hidesBottomBarWhenPushed = YES;
[navigationController pushViewController: otherController animated: TRUE];

Or you can set the property when you first initialize the controller you want to push.

I too struggled with this for a while. Hiding the tab bar is one step in the right direction, but leaves a black rectangle behind. The trick is to resize the layer that backs the UIViewController's view.

Don't use this solution!

BOOL hiddenTabBar;
UITabBarController *tabBarController;

- (void) hideTabBar {

     [UIView beginAnimations:nil context:NULL];
     [UIView setAnimationDuration:0.4];
     for(UIView *view in tabBarController.view.subviews)
     {
          CGRect _rect = view.frame;
          if([view isKindOfClass:[UITabBar class]])
          {
               if (hiddenTabBar) {
                    _rect.origin.y = [[UIScreen mainScreen] bounds].size.height-49;
                    [view setFrame:_rect];
               } else {
                    _rect.origin.y = [[UIScreen mainScreen] bounds].size.height;
                    [view setFrame:_rect];
               }
          } else {
               if (hiddenTabBar) {
                    _rect.size.height = [[UIScreen mainScreen] bounds].size.height-49;
                    [view setFrame:_rect];
               } else {
                    _rect.size.height = [[UIScreen mainScreen] bounds].size.height;
                    [view setFrame:_rect];
               }
          }
     }    
     [UIView commitAnimations];

     hiddenTabBar = !hiddenTabBar;
}
