推荐答案

如果要隐藏/显示视图的UITabBarController，请尝试以下操作:

Try this, if you want to hide/show the UITabBarController of view:

要隐藏标签栏:

 - (void)hideTabBar:(UITabBarController *) tabbarcontroller
 {
     for(UIView *view in tabbarcontroller.view.subviews)
     {
        if([view isKindOfClass:[UITabBar class]])
       {
           [view setFrame:CGRectMake(view.frame.origin.x, (isiPhone5?568:480), view.frame.size.width, view.frame.size.height)];
        }
        else
        {
           [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, isiPhone5?568: 480)];
        }
     }
  }

用于显示标签栏:

   - (void)showTabBar:(UITabBarController *) tabbarcontroller
     {

         for(UIView *view in tabbarcontroller.view.subviews)
         {
            if([view isKindOfClass:[UITabBar class]])
            {
               [view setFrame:CGRectMake(view.frame.origin.x,  (isiPhone5?519:431), view.frame.size.width, view.frame.size.height)];
            }
            else
            {
               [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width,  isiPhone5?519:431)];
            }
         }
      }

可能会有所帮助.
