@main
struct MyApp: App {
    @Environment(\.scenePhase) private var scenePhase
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .onChange(of: scenePhase) { phase in
            if phase == .background {
                // 应用程序进入后台时执行的操作
            }
        }
    }
}

struct ContentView: View {
    @Environment(\.scenePhase) private var scenePhase
    
    var body: some View {
        Text("Hello, World!")
            .padding()
            .onChange(of: scenePhase) { phase in
                if phase == .active {
                    // 应用程序进入前台时执行的操作
                }
            }
    }
}

if phase == .active {
    UIApplication.shared.beginReceivingRemoteControlEvents()
    let commandCenter = MPRemoteCommandCenter.shared()
    commandCenter.pauseCommand.isEnabled = false
    commandCenter.playCommand.isEnabled = false
    commandCenter.stopCommand.isEnabled = false
    commandCenter.togglePlayPauseCommand.isEnabled = false
}

if phase == .background {
    UIApplication.shared.endReceivingRemoteControlEvents()
