How to prevent screenshot for UIView in iOS?

by

iOS – Apple provides screenshot detection notification but not providing direct solution for prevention.

Here I found solution for preventing screenshot taking from the UIView. It’s a simple extension of the UIView that allows to hide it from screen-capturing and also from screen recording. The solution uses ability of UITextField to hide a password from capturing.

Usage:

viewSecure.preventScreenshot()

So, when you take screenshot the logic of text field secure entry (password text field) will not allow to take screenshot of that part.

ScrollView Screenshot Prevention

Update: Here is recursive function for preventing screenshot.

extension UIView {
func preventScrollViewScreenshotRecursive() {
guard superview != nil else {
for subview in subviews {
subview.preventScrollViewScreenshotRecursive()
}
return
}
let guardTextField = UITextField()
guardTextField.backgroundColor = .red
guardTextField.translatesAutoresizingMaskIntoConstraints = false
guardTextField.tag = Int.max
guardTextField.isSecureTextEntry = true
addSubview(guardTextField)
guardTextField.isUserInteractionEnabled = false
sendSubviewToBack(guardTextField)
layer.superlayer?.addSublayer(guardTextField.layer)
guardTextField.layer.sublayers?.first?.addSublayer(layer)
guardTextField.centerYAnchor.constraint(
equalTo: self.centerYAnchor
).isActive = true
guardTextField.centerXAnchor.constraint(
equalTo: self.centerXAnchor
).isActive = true
}
}
