Have you done some research if this is even possible in an native application?

While you’re thinking about this, consider how you’re going to handle the possibility of users pointing a camera at the screen.

Yeah and i didn’t find any solution in native :frowning_face:

My guess, you would need to jailbreak the device and mod the OS. And then build a capacitor/cordova plugin to trigger on/off API you patched into the OS.

Just trying to give a solution here…

Yes – it is possible. But you have to create your own Cordova or Capacitor Plugin :frowning:

How does it work?
In Swift you can create observers. These observers can observe screenshots or screen recordings too:

UIScreen.main.addObserver(self, forKeyPath: "captured", options: .new, context: nil)

Your plugin should now watch and receive this changes (is user is recording):

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey: Any]?, context: UnsafeMutableRawPointer?) {
    if (keyPath == "captured") {
        let isCaptured = UIScreen.main.isCaptured

        print(isCaptured)
    }
}

If the user is recording the Screen, the plugin could send a response to the App, and you could display a blank screen (for example a simple div with position fixed :+1:

Do you really need it?
Why do you want to prevent users from recording the screen? This is not very good for the User Experience.

It can take a few hours/days to create such a plugin, but (AFAIK) it is the only way to prevent users from recording the screen.

Wemaking an education app for client. he want to prevent any one from recording the courses videos

The only way I can think of to achieve this is to not distribute these videos, then.

I already mentioned one very simple recording strategy that will bypass anything you try to do in software: pointing a camera at the screen. Another would be to simply run the app in an emulator and do the screen capture on the host machine.
