How to hide UITabBar?
提问by Ilya Suzdalnitski
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:
在我的应用程序中，我有一个标签栏。在某些视图中，我也有一个工具栏。因此，当我使用工具栏访问这些视图时，它看起来很丑 - 视图底部有两个条。我认为在输入这些特定视图时隐藏标签栏是最好的解决方案。但我只是不知道如何以正确的方式做到这一点。我试图将 UITabBarController 的 tabBar 隐藏属性设置为 YES，但它不起作用。无论我是什么观点，我也试图做以下事情：
self.hidesBottomBarWhenPushed = YES;
But it didn't work as well.
但它也没有奏效。
What is the right solution to this situation? I don't want to have 2 bars at any view.
这种情况的正确解决方案是什么？我不想在任何角度都有 2 个酒吧。

You have to use set the hidesBottomBarWhenPushed property to YES on the controller that you are pushing and NOT to the UITabBarController.
您必须在要推送的控制器上将 hidesBottomBarWhenPushed 属性设置为 YES，而不是将其设置为 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.
或者您可以在首次初始化要推送的控制器时设置该属性。

Interface builder has checkbox for view controller embedded in tab bar - Hides bottom bar on push. In easy cases no need to do it through code now.
界面构建器具有嵌入在选项卡栏中的视图控制器复选框 - 在推送时隐藏底部栏。在简单的情况下，现在不需要通过代码来完成。

Don't use this solution!
不要使用此解决方案！
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;
}

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.
我也为此挣扎了一段时间。隐藏标签栏是朝着正确方向迈出的一步，但会留下一个黑色矩形。诀窍是调整支持 UIViewController 视图的层的大小。
I have written a small demo here with a solution:
