Live-Activities-Demo-NBA-Score

Live Activities and Dynamic Island Demo for NBA score

本Demo 已针对 Xcode15 beta 2 进行适配，并新增按钮来验证实时小组件可以支持按钮交互:

struct favorAppIntent: WidgetConfigurationIntent {
    static var title: LocalizedStringResource = "Configuration"
    static var description = IntentDescription("This is an example widget.")

    // An example configurable parameter.
    @Parameter(title: "Like")
    var teamId: String
    
    init() {
        
    }
    
    //to hold data
    init(teamId: String) {
        self.teamId = teamId
    }
    
    func perform() async throws -> some IntentResult {
        if let index = MatchDataManager.shared.teams.firstIndex(where: {
            $0.teamId == teamId
        }) {
            let resultTeam = MatchDataManager.shared.teams[index];
            resultTeam.likeNum += 10
            NBALiveTrigger.shared.updateLiveActivitiesLAVSWA()
        }
        
        return .result()
    }
}

添加按钮，首先要引入import AppIntents 框架，并区分系统版本:

if #available(iOS 17.0, *) {
...
 Button(intent: favorAppIntent(teamId: team.teamId)) {
    Image(systemName: "hand.thumbsup")
        .foregroundColor(.white)
 }
.buttonStyle(.plain)
}
} else {
// other View
}

创建Live Activities Target

Apple 在新的beta版中代码框架和补全给的更加完善，会自动帮咱们进行bundle的绑定和灵动岛相关代码的 新建Target选择Live Activities:

isLuminanceReduced 的应用

息屏时颜色处理 我们可以自定义一个边界的修饰器来给View添加息屏效果

struct LuminanceReducedColor: ViewModifier {
    var foregroundColor: Color
    @Environment(\.isLuminanceReduced) var isLuminanceReduced
    func body(content: Content) -> some View {
        if isLuminanceReduced {
            content.foregroundColor(.white)
        } else {
            content.foregroundColor(foregroundColor)
        }
    }
}

extension View {
    func luminanceReducedColor(color: Color) -> some View {
        modifier(LuminanceReducedColor(foregroundColor: color))
    }
}

Animation

Apple 对于这一块的动画限制比较多 动画测试代码:自定义一个动画

extension AnyTransition {
    static var moveAndFade: AnyTransition {
        .asymmetric(
            insertion: .move(edge: .bottom).combined(with: .opacity).combined(with: .scale(scale: 1.2)),
            removal: .scale.combined(with: .opacity)
        )
    }
}

关于Push更新

如果是个人开发者测试来使用 可以参考这位大佬的 https://github.com/rakutentech/macos-push-tester Push工具 修改相关的代码 build mac app PusherStore.swift 中 push func中添加

if data.pushtype == "liveactivity"{
  topic = "\(appBundleID).push-type.liveactivity"
}

StoryBoard中添加pushtype : liveactivity

运行后按照要求填写payload、证书、bundleId等信息 PS payload格式一定要按照你定义的contentstate字段 PS payload中timestamp 每次发送push都要变动，否则会出现无法更新的情况 Token使用控制台打印的token字符串
