在UIViewController上，我们可以很容易地将观测器添加到控制器中。比如：

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        NotificationCenter.default.addObserver(self, selector: #selector(didTakeScreenshot(notification:)), name: UIApplication.userDidTakeScreenshotNotification, object: nil)
    }
    
    @objc func didTakeScreenshot(notification: Notification) {
        print("Screen Shot Taken")
    }
}

或捕获记录：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    let isCaptured = UIScreen.main.isCaptured
    return true
}

下面是一个简单的demo：

struct ContentView: View {
    @State var isRecordingScreen = false
    
    var body: some View {
        Text("Test")
            .onReceive(NotificationCenter.default.publisher(for: UIApplication.userDidTakeScreenshotNotification)) { _ in
                print("Screenshot taken")
            }
            .onReceive(NotificationCenter.default.publisher(for: UIScreen.capturedDidChangeNotification)) { _ in
                isRecordingScreen.toggle()
                print(isRecordingScreen ? "Started recording screen" : "Stopped recording screen")
            }
    }
}

现在你可能想要EnvironmentValues.isSceneCaptured
iOS 17及以后
