Mac 上的 SwiftUI - 如何将按钮指定为主按钮? [英] SwiftUI on Mac - How do I designate a button as being the primary?

问题描述

在 AppKit 中，我会通过

解决方案

macOS 11.0/iOS 14:

从 Xcode 12 beta 开始，Button() 上公开了新方法，允许分配 keyEquivalent(通过枚举大小写或显式键和修饰符).

设置为默认值:

按钮( ... ).keyboardShortcut(.defaultAction)

设置为取消:

按钮( ... ).keyboardShortcut(.cancelAction)

In AppKit I would do this by assigning its key equivalent to be ↩ or making its cell the window's default. However, neither of these seems possible in SwiftUI, so how do I make a button the default window button?

解决方案

macOS 11.0 / iOS 14:

As of Xcode 12 beta, new methods are exposed on Button() allowing assignment of keyEquivalent (either by enum case or explicit key and modifiers).

Setting as default:

Button( ... )
    .keyboardShortcut(.defaultAction)

Setting as cancel:

Button( ... )
    .keyboardShortcut(.cancelAction)
