问题描述
我遇到了一个看起来很简单的问题.我的应用程序有一个视图层次结构，其中包含一个包含 UINavigationControllers 的 UITabBarController.当我从根导航到第二级时我将 hidesBottomBarWhenPushed 设置为 true，以便隐藏标签栏
I've a problem with something that seems to be very simple. My app has a view hierarchy consisting in a UITabBarController containing UINavigationControllers. When I navigate from the root to the second level I set the hidesBottomBarWhenPushed on true so that the tab bar is hidden
在我的 firstLevelController 上:
On my firstLevelController:
[secondLevelController setHidesBottomBarWhenPushed:YES];
[self.navigationController pushViewController:secondLevelController animated:YES];
之后，当我推到第三级时，我通过在 secondLevelController 中的操作再次带来标签栏:
After that when I push to the third level, I bring the tab bar again by doing in the secondLevelController:
[self setHidesBottomBarWhenPushed:NO];
[thirdLevelController setHidesBottomBarWhenPushed:NO];
[self.navigationController pushViewController:thirdLevelController animated:YES];
(我知道，我也不喜欢 [self setHidesBottomBarWhenPushed:NO]，但否则它不起作用......)
(I know, I didn't like the [self setHidesBottomBarWhenPushed:NO] either, but it didn´t work otherwise...)
所以，问题来了:当我在第三级按下后退按钮并出现第二个视图时，我需要再次隐藏标签栏，但我找不到这样做的方法.
感谢任何帮助
推荐答案
这对我有用.
[self setHidesBottomBarWhenPushed:NO];
[thirdLevelController setHidesBottomBarWhenPushed:NO];
[self.navigationController pushViewController:thirdLevelController animated:YES];
[self setHidesBottomBarWhenPushed:YES];
第三级控制器在弹出第三级控制器时显示标签栏，第二级控制器不显示标签栏.
The thirdlevelController shows the tabbar and secondLevelController does not show the tabbar when you pop the thirdLevelController.
