# Liquid Glass 设计系统 (iOS 26)

实现苹果 Liquid Glass 的模式指南——这是一种动态材质,会模糊其后的内容,反射周围内容的颜色和光线,并对触摸和指针交互做出反应。涵盖 SwiftUI、UIKit 和 WidgetKit 集成。

## 何时启用

* 为 iOS 26+ 构建或更新采用新设计语言的应用程序时
* 实现玻璃风格的按钮、卡片、工具栏或容器时
* 在玻璃元素之间创建变形过渡时
* 将 Liquid Glass 效果应用于小组件时
* 将现有的模糊/材质效果迁移到新的 Liquid Glass API 时

## 核心模式 — SwiftUI

### 基本玻璃效果

为任何视图添加 Liquid Glass 的最简单方法:

```swift
Text("Hello, World!")
    .font(.title)
    .padding()
    .glassEffect()  // Default: regular variant, capsule shape
```

### 自定义形状和色调

```swift
Text("Hello, World!")
    .font(.title)
    .padding()
    .glassEffect(.regular.tint(.orange).interactive(), in: .rect(cornerRadius: 16.0))
```

关键自定义选项:

* `.regular` — 标准玻璃效果
* `.tint(Color)` — 添加颜色色调以增强突出度
* `.interactive()` — 对触摸和指针交互做出反应
* 形状:`.capsule`(默认)、`.rect(cornerRadius:)`、`.circle`

### 玻璃按钮样式

```swift
Button("Click Me") { /* action */ }
    .buttonStyle(.glass)

Button("Important") { /* action */ }
    .buttonStyle(.glassProminent)
```

### 用于多个元素的 GlassEffectContainer

出于性能和变形考虑,始终将多个玻璃视图包装在一个容器中:

```swift
GlassEffectContainer(spacing: 40.0) {
    HStack(spacing: 40.0) {
        Image(systemName: "scribble.variable")
            .frame(width: 80.0, height: 80.0)
            .font(.system(size: 36))
            .glassEffect()

        Image(systemName: "eraser.fill")
            .frame(width: 80.0, height: 80.0)
            .font(.system(size: 36))
            .glassEffect()
    }
}
```

`spacing` 参数控制合并距离——距离更近的元素会将其玻璃形状融合在一起。

### 统一玻璃效果

使用 `glassEffectUnion` 将多个视图组合成单个玻璃形状:

```swift
@Namespace private var namespace

GlassEffectContainer(spacing: 20.0) {
    HStack(spacing: 20.0) {
        ForEach(symbolSet.indices, id: \.self) { item in
            Image(systemName: symbolSet[item])
                .frame(width: 80.0, height: 80.0)
                .glassEffect()
                .glassEffectUnion(id: item < 2 ? "group1" : "group2", namespace: namespace)
        }
    }
}
```

### 变形过渡

在玻璃元素出现/消失时创建平滑的变形效果:

```swift
@State private var isExpanded = false
@Namespace private var namespace

GlassEffectContainer(spacing: 40.0) {
    HStack(spacing: 40.0) {
        Image(systemName: "scribble.variable")
            .frame(width: 80.0, height: 80.0)
            .glassEffect()
            .glassEffectID("pencil", in: namespace)

        if isExpanded {
            Image(systemName: "eraser.fill")
                .frame(width: 80.0, height: 80.0)
                .glassEffect()
                .glassEffectID("eraser", in: namespace)
        }
    }
}

Button("Toggle") {
    withAnimation { isExpanded.toggle() }
}
.buttonStyle(.glass)
```

### 将水平滚动延伸到侧边栏下方

要允许水平滚动内容延伸到侧边栏或检查器下方,请确保 `ScrollView` 内容到达容器的 leading/trailing 边缘。当布局延伸到边缘时,系统会自动处理侧边栏下方的滚动行为——无需额外的修饰符。

## 核心模式 — UIKit

### 基本 UIGlassEffect

```swift
let glassEffect = UIGlassEffect()
glassEffect.tintColor = UIColor.systemBlue.withAlphaComponent(0.3)
glassEffect.isInteractive = true

let visualEffectView = UIVisualEffectView(effect: glassEffect)
visualEffectView.translatesAutoresizingMaskIntoConstraints = false
visualEffectView.layer.cornerRadius = 20
visualEffectView.clipsToBounds = true

view.addSubview(visualEffectView)
NSLayoutConstraint.activate([
    visualEffectView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
    visualEffectView.centerYAnchor.constraint(equalTo: view.centerYAnchor),
    visualEffectView.widthAnchor.constraint(equalToConstant: 200),
    visualEffectView.heightAnchor.constraint(equalToConstant: 120)
])

// Add content to contentView
let label = UILabel()
label.text = "Liquid Glass"
label.translatesAutoresizingMaskIntoConstraints = false
visualEffectView.contentView.addSubview(label)
NSLayoutConstraint.activate([
    label.centerXAnchor.constraint(equalTo: visualEffectView.contentView.centerXAnchor),
    label.centerYAnchor.constraint(equalTo: visualEffectView.contentView.centerYAnchor)
])
```

### 用于多个元素的 UIGlassContainerEffect

```swift
let containerEffect = UIGlassContainerEffect()
containerEffect.spacing = 40.0

let containerView = UIVisualEffectView(effect: containerEffect)

let firstGlass = UIVisualEffectView(effect: UIGlassEffect())
let secondGlass = UIVisualEffectView(effect: UIGlassEffect())

containerView.contentView.addSubview(firstGlass)
containerView.contentView.addSubview(secondGlass)
```

### 滚动边缘效果

```swift
scrollView.topEdgeEffect.style = .automatic
scrollView.bottomEdgeEffect.style = .hard
scrollView.leftEdgeEffect.isHidden = true
```

### 工具栏玻璃集成

```swift
let favoriteButton = UIBarButtonItem(image: UIImage(systemName: "heart"), style: .plain, target: self, action: #selector(favoriteAction))
favoriteButton.hidesSharedBackground = true  // Opt out of shared glass background
```

## 核心模式 — WidgetKit

### 渲染模式检测

```swift
struct MyWidgetView: View {
    @Environment(\.widgetRenderingMode) var renderingMode

    var body: some View {
        if renderingMode == .accented {
            // Tinted mode: white-tinted, themed glass background
        } else {
            // Full color mode: standard appearance
        }
    }
}
```

### 用于视觉层次结构的强调色组

```swift
HStack {
    VStack(alignment: .leading) {
        Text("Title")
            .widgetAccentable()  // Accent group
        Text("Subtitle")
            // Primary group (default)
    }
    Image(systemName: "star.fill")
        .widgetAccentable()  // Accent group
}
```

### 强调模式下的图像渲染

```swift
Image("myImage")
    .widgetAccentedRenderingMode(.monochrome)
```

### 容器背景

```swift
VStack { /* content */ }
    .containerBackground(for: .widget) {
        Color.blue.opacity(0.2)
    }
```

## 关键设计决策

| 决策 | 理由 |
|----------|-----------|
| 使用 GlassEffectContainer 包装 | 性能优化,实现玻璃元素之间的变形 |
| `spacing` 参数 | 控制合并距离——微调元素需要多近才能融合 |
| `@Namespace` + `glassEffectID` | 在视图层次结构变化时实现平滑的变形过渡 |
| `interactive()` 修饰符 | 明确选择加入触摸/指针反应——并非所有玻璃都应响应 |
| UIKit 中的 UIGlassContainerEffect | 与 SwiftUI 保持一致的容器模式 |
| 小组件中的强调色渲染模式 | 当用户选择带色调的主屏
