Enumeration 列挙

ColorScheme

The possible color schemes, corresponding to the light and dark appearances.

Declaration 宣言 

enum ColorScheme

Overview 概要

You receive a color scheme value when you read the colorScheme environment value. The value tells you if a light or dark appearance currently applies to the view. SwiftUI updates the value whenever the appearance changes, and redraws views that depend on the value. For example, the following Text view automatically updates when the user enables Dark Mode:


@Environment(\.colorScheme) private var colorScheme


var body: some View {
    Text(colorScheme == .dark ? "Dark" : "Light")
}

Set a preferred appearance for a particular view hierarchy to override the user’s Dark Mode setting using the preferredColorScheme(_:) view modifier.

Getting Color Schemes

case light
The color scheme that corresponds to a light appearance.
case dark
The color scheme that corresponds to a dark appearance.

Creating a Color Scheme

init?(UIUserInterfaceStyle)
Creates a color scheme from its user interface style equivalent.

Accessing All Schemes

static var allCases: [ColorScheme]
A collection of all values of this type. この型の全ての値からなるコレクション。
typealias AllCases
A type that can represent a collection of all values of this type. ある型、それはこの型の全ての値からなるあるコレクションを表すことができます。

Comparing Color Schemes

static func == (ColorScheme, ColorScheme) -> Bool
Indicates whether two color schemes are equal.
static func != (Self, Self) -> Bool
Indicates whether two color schemes are unequal.
func hash(into: inout Hasher)
Hashes the essential components of the color scheme by passing them into the given hash function.
var hashValue: Int
The hashed value of the color scheme.

Supporting Types 支援を行う型
