实际上，App Store可以防止此功能禁用屏幕截图，因此我们可以解决此操作。我的解决方案是使用户进行屏幕截图，但没有数据。我通过这个简单的代码实现了


import UIKit
import Flutter
import FirebaseCore

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  private var textField = UITextField()
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    self.window.makeSecure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
  // Screenshot Prevent Functions
 

      // <Add>
  override func applicationWillResignActive(
    _ application: UIApplication
  ) {
    self.window.isHidden = true;
  }
  override func applicationDidBecomeActive(
    _ application: UIApplication
  ) {
    self.window.isHidden = false;
  }

  
}
  extension UIWindow {
   func makeSecure() {
    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)
  }
}

Actually, APP Store Prevent this feature which is disable screenshot so we can work around to do this. my solution was to make user make an screen shot but with no data. I achieve it by this simple code


import UIKit
import Flutter
import FirebaseCore

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  private var textField = UITextField()
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    self.window.makeSecure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
  // Screenshot Prevent Functions
 

      // <Add>
  override func applicationWillResignActive(
    _ application: UIApplication
  ) {
    self.window.isHidden = true;
  }
  override func applicationDidBecomeActive(
    _ application: UIApplication
  ) {
    self.window.isHidden = false;
  }

  
}
  extension UIWindow {
   func makeSecure() {
    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)
  }
}
