SwiftUI 中 Text 对象中使用的当前字体 [英] Current font used in a Text object in SwiftUI

问题描述

有没有办法在 SwiftUI 中获取/获取 Text 对象中使用的当前字体?前任.Text("abc").font() 不起作用.

Is there a way to get/obtain the current font used in a Text object in SwiftUI? ex. Text("abc").font() does not work.

推荐答案

当前字体可从环境访问:

The current font is accessible from the environment:

struct ChildView: View {
    @Environment(\.font) var font

    var body: some View {
        Text("Italic version of the hierarchy's font")
            .font((font ?? .body).italic())
    }
}

请参阅 https://developer.apple.com/documentation/swiftui/environmentvalues 有关可用密钥的完整列表，它们可以派上用场.
