Prevent Screenshot of UIView - iOS

PreventScreenshot.swift

extension UIView {
    func preventScreenshot() {
        DispatchQueue.main.async {
            let field = UITextField()
            field.isSecureTextEntry = true
            self.addSubview(field)
            field.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
            field.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
            self.layer.superlayer?.addSublayer(field.layer)
            field.layer.sublayers?.first?.addSublayer(self.layer)
        }
    }
}

This no longer works in iOS17 (beta at least).

Yes. I have also tested. Specifically above code is not working in iOS 17. I am also looking into it.

Meanwhile you can check following gist and screenshot prevention, which is totally working fine in iOS 17 too.

Thanks for the new example. I will check it out.
Still curious what's the big difference here, but thanks again for looking into it!

any solution for ios 17?

@ashishkakkad8 Did you find any solution?

@awnigharbia As I have written above. I have already tested the https://gist.github.com/ashishkakkad8/695e0b1828f699ed538bcf1a01920cc7 code and it was working fine in iOS 17 beta. I didn't get time to check in latest versions. Once I get time sure I will check. Thanks :)

Thanks I managed to solve it.

If you found anything please post it in this thread. Thank you.

@awnigharbia how?

how to use this on table view???

apple has warned not to use such methods of adding view's layer to another view's layer, this will break you UI. https://forums.developer.apple.com/forums/thread/722333
