How to hide UITabBar?

In my app I have a tab bar. And in some views I as well have a toolbar. So when I come to those views with a toolbar it looks ugly - two bars at the bottom of the view. I thought that it would be a best solution to hide a tab bar when entering those particular views. But I just couldn't figure out how to do it in a right way. I tried to set UITabBarController's tabBar hidden property to YES, but it didn't work. And I as well tried to do the following thing in whatever view I am:

self.hidesBottomBarWhenPushed = YES;

But it didn't work as well.

What is the right solution to this situation? I don't want to have 2 bars at any view.

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.

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;
}

There is no built in way to hide the tab bar for your current view.

You can hide it when pushing a view with the hidesBottomBarWhenPushed variable.

If you want to hide your tab bar on your current view, you can do the following:

Note that UIKit seems to bring the tab bar to come back on app resume. So you will have to subscribe to the notification UIApplication.didBecomeActiveNotification and call the above function.
