ScreenProtec

ScreenProtec is a simple utility class for iOS applications that leverages UITextField's isSecureTextEntry property to prevent users from capturing screenshots. It works by overlaying a secure text field on the application's main window.

Features

• Screenshot Prevention: Blocks screenshots by utilizing UITextField's secure text entry feature.
• Easy Integration: Minimal configuration required to activate screenshot protection.
• Version Handling: Ensures compatibility with iOS 17 and earlier versions.

Usage

Step 1: Initialization

Initialize a ScreenProtec instance in your SceneDelegate:

let screenProtec = ScreenProtec(window: window)

Step 2: Configure Protection

Configure the protection layer:

screenProtec.configurePreventionScreenshot()

Step 3: Enable Screenshot Prevention

Enable the screenshot prevention mechanism:

screenProtec.enabledPreventScreenshot()

Optional: Disable Screenshot Prevention

If you want to disable screenshot prevention:

screenProtec.disablePreventScreenshot()

Installation

To add ScreenProtec to your project, you can:

1. Download the source file ScreenProtec.swift and add it to your project.
2. Import the necessary UIKit framework in your file if not already done.

Example Code

Example usage in SceneDelegate.

func scene(_ scene: UIScene,
             willConnectTo session: UISceneSession,
             options connectionOptions: UIScene.ConnectionOptions) {
      guard let _ = (scene as? UIWindowScene) else { return }
      
      let screenProtec = ScreenProtec(window: window)
      screenProtec.configurePreventionScreenshot()
      screenProtec.enabledPreventScreenshot()
}

Limitations

• The solution leverages UITextField's isSecureTextEntry property, which may not be foolproof in all scenarios.
• Behavior may vary depending on iOS version and system-specific security mechanisms.
