objective-c - UIModalPresentationStyle.FormSheet 在 iPad 上始终全屏显示 (SWIFT)

Question

我正在尝试将一些 Objective-C 代码转换为 SWIFT。

我正在将 UIViewController 作为表单加载。这是 objective-c 中的代码:

generalPopup.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
generalPopup.modalPresentationStyle = UIModalPresentationFormSheet;

这是 Swift 中的代码:

generalPopup.modalTransitionStyle = UIModalTransitionStyle.CoverVertical
generalPopup.modalPresentationStyle = UIModalPresentationStyle.FormSheet

在 Objective-C 中， View 显示为 FormSheet。在 swift 中，CoverVertical 得以保留，但 View 占据了整个屏幕，而不是显示为 FormSheet。

提醒一下，根据 Apple 的说法，FormSheet 是:

A view presentation style in which the width and height of the presented view are smaller than those of the screen and the view is centered onscreen. If the device is in a landscape orientation and the keyboard is visible, the position of the view is adjusted upward so the view remains visible. All uncovered areas are dimmed to prevent the user from interacting with them.

Answer 1

继续引用文档中的内容:

In a horizontally compact environment, this option behaves the same as UIModalPresentationFullScreen.

看起来你有一个“水平紧凑的环境”。检查 swift 项目中的 Storyboard设置。
