SwiftUI 和 Liquid Glass 设计系统
革命性设计语言实现

Liquid Glass 代表了自扁平设计引入以来最重要的设计演进。这种半透明材料系统创造了深度和视觉层次,同时保持苹果对清晰度和功能性的承诺。
核心 Liquid Glass 原则:
- 半透明性:反射和折射底层内容的玻璃效果
- 动态适应:基于内容的自动浅色到深色过渡
- 深度感知:多层视觉层次
- 交互响应性:用户交互期间的玻璃变形
SwiftUI 实现:
基本玻璃效果:
struct GlassCard: View {
var body: some View {
VStack {
Text("玻璃效果")
.font(.headline)
Text("具有半透明背景的内容")
.font(.body)
}
.padding()
.glassEffect() // SwiftUI 中的新修饰符
.cornerRadius(12)
}
}
高级玻璃自定义:
struct CustomGlassView: View {
var body: some View {
Rectangle()
.fill(.clear)
.glassEffect(
style: .prominent,
blendMode: .overlay,
opacity: 0.8
)
.overlay {
VStack {
Image(systemName: "star.fill")
.font(.largeTitle)
Text("高级功能")
.font(.headline)
}
.foregroundStyle(.primary)
}
}
}
交互式玻璃组件:
struct LiquidGlassButton: View {
@State private var isPressed = false
var body: some View {
Button("Liquid Glass 按钮") {
// 操作
}
.padding()
.glassEffect(
style: isPressed ? .regular : .prominent,
animated: true
)
.scaleEffect(isPressed ? 0.95 : 1.0)
.onPressGesture(
pressing: { pressing in
withAnimation(.easeInOut(duration: 0.1)) {
isPressed = pressing
}
},
perform: {}
)
}
}
跨平台设计一致性
统一玻璃框架:
// 单一实现适用于所有平台
struct UniversalGlassContainer<Content: View>: View {
let content: Content
init(@ViewBuilder content: () -> Content) {
self.content = content()
}
var body: some View {
content
.padding()
.glassEffect()
.cornerRadius(platformSpecificRadius())
}
private func platformSpecificRadius() -> CGFloat {
#if os(iOS)
return 16
#elseif os(macOS)
return 12
#elseif os(watchOS)
return 8
#else
return 12
#endif
}
}
平台自适应组件:
- 导航栏:具有平台适当行为的浮动玻璃导航
- 标签栏:iPhone 上的紧凑外观,iPad 和 Mac 上的扩展外观
- 工具栏:状态转换期间的动态玻璃变形
- 侧边栏:适应内容密度的半透明侧边栏
高级玻璃效果和动画
角落同心性:
struct ConcentricGlassView: View {
var body: some View {
RoundedRectangle(cornerRadius: 16)
.fill(.clear)
.glassEffect()
.overlay {
RoundedRectangle(cornerRadius: 12)
.stroke(.white.opacity(0.2), lineWidth: 1)
.padding(4)
}
.overlay {
RoundedRectangle(cornerRadius: 8)
.stroke(.white.opacity(0.1), lineWidth: 0.5)
.padding(8)
}
}
}
动态玻璃过渡:
struct TransitioningGlass: View {
@State private var isExpanded = false
var body: some View {
VStack {
if isExpanded {
DetailContent()
.transition(.glassSlide)
}
}
.glassEffect(
style: isExpanded ? .prominent : .regular,
animated: true
)
.animation(.glassSpring(duration: 0.6), value: isExpanded)
}
}
extension AnyTransition {
static var glassSlide: AnyTransition {
.asymmetric(
insertion: .move(edge: .top).combined(with: .opacity),
removal: .move(edge: .bottom).combined(with: .opacity)
)
}
}
extension Animation {
static func glassSpring(duration: Double) -> Animation {
.interpolatingSpring(
mass: 0.8,
stiffness: 100,
damping: 10,
initialVelocity: 0
)
.speed(1 / duration)
}
}

func generateText(prompt: String) async throws -> String {
let request = TextGenerationRequest(
prompt: prompt,
maxTokens: 200,
temperature: 0.7,
topP: 0.9
)
let response = try await model.generateText(request)
return response.generatedText
}
}
带约束的引导生成:
@Generable
struct EmailResponse {
let subject: String
let body: String
let tone: EmailTone
let priority: Priority
}
enum EmailTone: String, CaseIterable {
case formal, casual, friendly, professional
}
enum Priority: String, CaseIterable {
case low, medium, high, urgent
}
class EmailAssistant {
func generateEmail(context: String) async throws -> EmailResponse {
let prompt = "为以下内容生成电子邮件回复:\(context)"
return try await FoundationModel.shared.generate(
EmailResponse.self,
prompt: prompt
)
}
}
工具调用实现:
protocol AITool {
var name: String { get }
var description: String { get }
func execute(parameters: [String: Any]) async throws -> String
}
struct WeatherTool: AITool {
let name = "get_weather"
let description = "获取位置的当前天气"
func execute(parameters: [String: Any]) async throws -> String {
guard let location = parameters["location"] as? String else {
throw AIError.invalidParameters
}
// 与天气服务集成
let weather = try await WeatherService.current(for: location)
return "\(location) 的当前天气:\(weather.description)"
}
}
class AIAssistantWithTools {
private let tools: [AITool] = [WeatherTool()]
func processRequest(_ input: String) async throws -> String {
let response = try await FoundationModel.shared.processWithTools(
input: input,

func analyzeImage(_ image: UIImage, question: String) async throws -> String {
// 将图像转换为适当格式
guard let imageData = image.jpegData(compressionQuality: 0.8) else {
throw AIError.imageProcessingFailed
}
let request = MultimodalRequest(
image: imageData,
prompt: question,
maxTokens: 150
)
let response = try await FoundationModel.shared.processMultimodal(request)
return response.analysis
}
}
// 使用示例
let imageAnalyzer = MultimodalAI()
let result = try await imageAnalyzer.analyzeImage(
userImage,
question: "这栋建筑展示了什么建筑风格?"
)
自定义模型训练:
// Swift 中的 Python 风格训练配置
struct CustomTrainingConfig {
let baseModel: String = "foundation-3b"
let trainingData: URL
let rank: Int = 32
let learningRate: Double = 0.0001
let epochs: Int = 10
}
class CustomModelTrainer {
func trainSpecializedModel(config: CustomTrainingConfig) async throws -> URL {
let trainer = FoundationModelTrainer(config: config)
// 训练在设备上进行以保护隐私
let modelURL = try await trainer.train()
// 保存以供后续使用
try await FoundationModel.shared.loadCustomModel(from: modelURL)
return modelURL
}
}

private let queue = DispatchQueue(label: "ai.processing", qos: .userInitiated)
func processWithCaching(_ input: String) async throws -> String {
let cacheKey = NSString(string: input.hash.description)
if let cachedResponse = cache.object(forKey: cacheKey) {
return cachedResponse.text
}
let response = try await FoundationModel.shared.generate(
prompt: input,
cachePolicy: .preferCache
)
cache.setObject(response, forKey: cacheKey)
return response.text
}
}
