Complete prevention of ios screeen shot

[SAHILDEWAN23]

Try this - this will restrict the entire window.

func makeSecure(window: UIWindow) {

        let field = UITextField()



        let view = UIView(frame: CGRect(x: 0, y: 0, width: field.frame.self.width, height: field.frame.self.height))



        let image = UIImageView(image: UIImage(named: "whiteImage"))

        image.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)



        field.isSecureTextEntry = true



        window.addSubview(field)

        view.addSubview(image)



        window.layer.superlayer?.addSublayer(field.layer)

        field.layer.sublayers?.last!.addSublayer(window.layer)



        field.leftView = view

        field.leftViewMode = .always

}

I am using expo reactnative will this work on that if i made prebuild and insert this into Appdelegate or there is any different way for that.... will this also get accepted by app store?

This crashes on iPads supporting multiple windows due the the cycle created here:
window.layer.superlayer?.addSublayer(field.layer) field.layer.sublayers?.last!.addSublayer(window.layer)

window.layer → field.layer → … → window.layer

and hence recursively calls _recursiveEagerlyUpdateSafeAreaInsetsUntilViewController and eventually the app crashes.
