我有一个具有受版权保护的内容的应用程序。我不希望用户记录它。如果他们开始录制屏幕,我希望我的应用程序能够捕捉到这一点。如果正在录屏,用什么函数来捕捉?
我不想阻止,我想理解并抓住它。
注意:一些答案表示解决方案包括 AirPlay 和镜像。我想要的是只捕获在应用程序之前或期间开始的屏幕录制。我想允许用户使用 AirPlay 和 Mirroring。

为了防止屏幕录制,我创建了一个单独的类ScreenRecordingProtoector
女巫看起来像这样:
final class ScreenRecordingProtoector {
private var window: UIWindow? {
if #available(iOS 13.0, *) {
return (UIApplication.shared.connectedScenes.first?.delegate as? SceneDelegate)?.window
}
return (UIApplication.shared.delegate as? AppDelegate)?.window
}
func startPreventing() {
NotificationCenter.default.addObserver(self, selector: #selector(preventScreenShoot), name: UIScreen.capturedDidChangeNotification, object: nil)
}
@objc private func preventScreenShoot() {
if #available(iOS 13.0, *) {
if UIScreen.main.isCaptured {
window?.isHidden = true
} else {
window?.isHidden = false
}
}
}
// MARK: - Deinit
deinit {
NotificationCenter.default.removeObserver(self)
}
}

然后我只需在上面的 AppDelegate 中创建一个变量didFinishLaunchingWithOptions let screenRecordingProtoector = ScreenRecordingProtoector(),然后在里面调用didFinishLaunchingWithOptions screenRecordingProtoector.startPreventing()
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
private let preventService = PreventCapturingService()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
preventService.startPreventScreenRecording()
return true
}
}
