在 iOS 13 全屏中呈现模式

Presenting modal in iOS 13 fullscreen(在 iOS 13 全屏中呈现模式)

问题描述

在 iOS 13 中，模态视图控制器在呈现时具有新的行为.

In iOS 13 there is a new behaviour for modal view controller when being presented.

现在它默认不是全屏的，当我尝试向下滑动时，应用程序会自动关闭视图控制器.

Now it's not fullscreen by default and when I try to slide down, the app just dismiss the View Controller automatically.

如何防止这种行为并恢复到旧的全屏模式 vc?

How can I prevent this behaviour and get back to the old fullscreen modal vc?

谢谢

推荐答案

使用 iOS 13，如 Platforms State of the Union 在 WWDC 2019 期间，Apple 推出了新的默认卡片演示.为了强制全屏，您必须明确指定它:

With iOS 13, as stated in the Platforms State of the Union during the WWDC 2019, Apple introduced a new default card presentation. In order to force the fullscreen you have to specify it explicitly with:

let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen //or .overFullScreen for transparency
self.present(vc, animated: true, completion: nil)
