问题描述
我正在使用 TabBarController，并且从其中一个选项卡中，我想呈现另一个 UIViewController，同时保持 TabBar 的显示.
I am using a TabBarController, and from one of the tabs, I want to present another UIViewController, while keeping the TabBar displayed.
如果我只是呈现或推动视图控制器，它会全屏显示，位于 TabBar 上方.
If I simply present or push the view controller, it is displayed in full screen, above the TabBar.
解决这个问题的正确方法是什么?
What is the right way to solve this issue?
推荐答案
假设 ViewControllerA 是 TabBarController 的 UIViewController.而你想要呈现的 UIViewController 是 ViewControllerB
Assume ViewControllerA is a UIViewController of TabBarController. And the UIViewController you want to present is ViewControllerB
推送 ViewControllerB，同时保持 TabBar 显示.只需在 ViewControllerA 中调用
To push ViewControllerB, while keeping the TabBar displayed. Simply inside ViewControllerA you just need to call
ViewControllerB *vc = // Initialize ViewControllerB here
[self.navigationController pushViewController:vc animated:YES];
呈现ViewControllerB
ViewControllerB *vc = Initialize ViewControllerB here
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:vc animated:YES completion:nil];
在演示时，请确保为 ViewControllerB 的 modalPresentationStyle 属性设置了 UIModalPresentationOverCurrentContext.如果没有，它将在 TabBar
With presenting, make sure you set UIModalPresentationOverCurrentContext for modalPresentationStyle property of ViewControllerB. If not, it will present fullscreen, over the TabBar
为了更容易理解，我创建了一个演示仓库，你可以看看.
For easier understanding, i created a demo repo, you can take a look.
