我有问题UITabBarController。在我的应用程序中，我想隐藏它但没有使用，hidesBottomBarWhenPushed因为我想隐藏它而不是当我推它时。例如，我想在我的应用程序中按“隐藏”按钮时隐藏它。

Answer 1

我从我的工作代码中粘贴这个...你可以调用这些方法来隐藏和显示tabbarcontroller ....只需将tabbarcontroller实例传递给这些函数..// Method call[self hideTabBar:self.tabBarController];// Method implementations- (void)hideTabBar:(UITabBarController *) tabbarcontroller{     [UIView beginAnimations:nil context:NULL];     [UIView setAnimationDuration:0.5];     for(UIView *view in tabbarcontroller.view.subviews)     {         if([view isKindOfClass:[UITabBar class]])         {             [view setFrame:CGRectMake(view.frame.origin.x, 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, 480)];         }     }     [UIView commitAnimations];   }- (void)showTabBar:(UITabBarController *) tabbarcontroller{            [UIView beginAnimations:nil context:NULL];     [UIView setAnimationDuration:0.5];     for(UIView *view in tabbarcontroller.view.subviews)     {         NSLog(@"%@", view);         if([view isKindOfClass:[UITabBar class]])         {             [view setFrame:CGRectMake(view.frame.origin.x, 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, 431)];         }     }     [UIView commitAnimations]; }

改进的Setomidor对横向，纵向和iPad工作的回答（320和480值仅适用于iPhone）。- (void) hideTabBar:(UITabBarController *) tabbarcontroller  {     CGRect screenRect = [[UIScreen mainScreen] bounds];     [UIView beginAnimations:nil context:NULL];     [UIView setAnimationDuration:0.5];     float fHeight = screenRect.size.height;     if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )     {         fHeight = screenRect.size.width;     }     for(UIView *view in tabbarcontroller.view.subviews)     {         if([view isKindOfClass:[UITabBar class]])         {             [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];         }          else          {             [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];             view.backgroundColor = [UIColor blackColor];         }     }     [UIView commitAnimations];}- (void) showTabBar:(UITabBarController *) tabbarcontroller  {        CGRect screenRect = [[UIScreen mainScreen] bounds];     float fHeight = screenRect.size.height - tabbarcontroller.tabBar.frame.size.height;     if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )     {         fHeight = screenRect.size.width - tabbarcontroller.tabBar.frame.size.height;     }     [UIView beginAnimations:nil context:NULL];     [UIView setAnimationDuration:0.5];     for(UIView *view in tabbarcontroller.view.subviews)     {            if([view isKindOfClass:[UITabBar class]])         {             [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];                     }          else          {             [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];         }            }     [UIView commitAnimations]; }还修改了代码以处理iOS 6中引入的更改，并更改了UIDevice方向，并确保即使设备背面也能正常工作。
