Is there any way to disable the screen recording? or is is possible through a configuration profile? or any third party library is available?

NotificationCenter.default.addObserver(self, selector: #selector(preventScreenRecording), name: NSNotification.Name.UIScreenCapturedDidChange, object: nil)

And create a view inside main view and prevent like that.

(void) preventScreenRecording {
if (@available(iOS 11.0, *)) {
    BOOL isCaptured = [[UIScreen mainScreen] isCaptured];

    if (isCaptured) {
        self.blockView.hidden = false;
    }
    else {
        self.blockView.hidden = true;
    }
}

Can you explain what is blockView here? And I believe this method is called after screenshot is captured. I haven't tested it yet – NightFury Jan 13 '20 at 10:26

@NightFury blockView is the area that you want to disable screenRecording. – PPShein Feb 12 '20 at 01:34
@SagarDaundkar I think it would be same as what I mentioned. – PPShein Feb 12 '20 at 01:34

When your app is started you can test UIScreen.isCaptured property and show some splash screen if it's set to true.

You should also observe (subscribe in some place for) capturedDidChangeNotification notification, and do same thing (show splash screen) if UIScreen.isCaptured is set to true.

Swift 4 and above

You just need to make the following changes in your Appdelegate.swift page.

It will automatically add a blurred view on the top of the app when the user tries to record the screen.

weak var screen : UIView? = nil

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    NotificationCenter.default.addObserver(self, selector: #selector(preventScreenRecording), name: UIScreen.capturedDidChangeNotification, object: nil)
    return true
}

@objc func preventScreenRecording() {
    let isCaptured = UIScreen.main.isCaptured
    print("isCaptured: \(isCaptured)")
    if isCaptured {
        blurScreen()
    }
    else {
        removeBlurScreen()
    }
}

func blurScreen(style: UIBlurEffect.Style = UIBlurEffect.Style.regular) {
    screen = UIScreen.main.snapshotView(afterScreenUpdates: false)
    let blurEffect = UIBlurEffect(style: style)
    let blurBackground = UIVisualEffectView(effect: blurEffect)
    screen?.addSubview(blurBackground)
    blurBackground.frame = (screen?.frame)!
    window?.addSubview(screen!)
}

func removeBlurScreen() {
    screen?.removeFromSuperview()
}

sharedRecorder.stopRecording( handler: { previewViewController, error in    
    if let error = error {
        print("\(error.localizedDescription)")
    }
    if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad {
        previewViewController?.modalPresentationStyle = UIModalPresentationStyle.popover
        previewViewController?.popoverPresentationController?.sourceRect = CGRect.zero
        previewViewController?.popoverPresentationController?.sourceView = self.view
    }
    if previewViewController != nil {
        self.previewViewController = previewViewController
        previewViewController?.previewControllerDelegate = self
    }
    self.present(previewViewController!, animated: true, completion: nil)
    })
    return
}
