在子视图上隐藏选项卡栏控制器

发布于 2024-12-21 10:14:12 字数 716 浏览 4 评论 0原文

我发现这个问题有很多变化，但只是想澄清一下，因为我似乎无法让我的工作发挥作用。

我有一个 TabBarController (TBC)，其中包含多个 UIViewController（每个选项卡）。在其中一个 UIViewController (mainMenu) 上，我尝试添加另一个 UIViewController (game1) 作为子视图：

[self.view addSubview:game1.view];

现在的问题是，它需要 TBC它，所以我尝试使用以下方法隐藏它：

self.hidesBottomBarWhenPushed = YES; //< (In the game1.m ViewDidLoad method)

我

game1.hidesBottomBarWhenPushed = YES; //< (In the mainMenu.m after I initialise game1)

猜测这是因为当我使用 addSubview 方法时菜单从未被推送？

最初我使用的是 presentModalViewController 方法，但框架被传递到新视图上，从而导致 UI 布局偏移/放大。

任何人都可以帮我解决这个问题，我似乎无法隐藏 TBC，我已经没有主意了。

提前致谢，埃利奥特

I have found lot's of variations for this question but just wanted some clarity on it as I can't seem to get mine working.

I have a TabBarController (TBC) which contains several UIViewControllers (Each Tab). On one of these UIViewControllers (mainMenu), I am trying to add another UIViewController (game1) as a subview:

[self.view addSubview:game1.view];

Now the issue with this is that it takes the TBC with it, so I tried hiding it using:

self.hidesBottomBarWhenPushed = YES; //< (In the game1.m ViewDidLoad method)

and

game1.hidesBottomBarWhenPushed = YES; //< (In the mainMenu.m after I initialise game1)

I am guessing that this is due to the menu never being pushed as I am using the addSubview approach?

Originally I was using the presentModalViewController approach but the frame is being passed onto the new view, thus causing the UI layout to be offset / zoomed in.

Can anyone help me fix this issue, I can't seem to hide the TBC and am running out of ideas.

Thanks in advanced, Elliott

hidesBottomBarWhenPushed 仅当您将视图控制器推送到 UINavigationController 堆栈时才相关。您使用 addSubview: 所做的就是将 game1 的视图添加到当前视图控制器的视图中。这是完全不对的，UIKit 根本不会处理这个问题。

您应该将 UINavigationController 作为选项卡的视图控制器，然后使用类似以下内容的内容推送 game1 视图控制器：

[self.navigationController pushViewController:game1 animated:YES];

而不是 addSubview:。然后，这将与 hidesBottomBarWhenPushed 一起使用。但请注意，最好在 game1 类的 init 方法中设置 hidesBottomBarWhenPushed，而不是在 viewDidLoad 中设置代码>.

hidesBottomBarWhenPushed is only relevant when you're pushing the view controller onto a UINavigationController stack. What you're doing with the addSubview: is that you're just adding the view of game1 into the current view controller's view. That is not right at all and UIKit won't handle that at all.

You should put a UINavigationController as the view controller for your tab, then push the game1 view controller with something like:

[self.navigationController pushViewController:game1 animated:YES];

instead of addSubview:. That will then work with hidesBottomBarWhenPushed. Note however that it's probably best to set hidesBottomBarWhenPushed in the your init method of whatever class game1 is, rather than in viewDidLoad.
