问颤振: FlutterWindowManager.FLAG_SECURE不适用于ios

EN

在iOS上，我在扩展https://stackoverflow.com/a/67054892/4899849的帮助下禁用了截图。接下来的步骤如下：

AppDelegatevar field = UITextField()中的

1. 添加属性

1. in didFinishLaunchingWithOptions调用下一个方法：addSecuredView()

私有函数field.layer.sublayers?.first?.addSublayer(window.layer) (){ if (！window.subviews.contains(字段)){window.addSubview(字段) field.centerYAnchor.constraint(equalTo: window.centerYAnchor).isActive = true field.centerXAnchor.constraint(equalTo: window.centerXAnchor).isActive = true field.layer.sublayers？.first？.addSublayer(window.layer)}

}

1. 重写委托方法：

重写func applicationWillResignActive(_ application: UIApplication) { field.isSecureTextEntry = false }覆盖func applicationDidBecomeActive(_ application: UIApplication) { field.isSecureTextEntry = true }

现在，当您在应用程序中制作屏幕快照或录制屏幕视频时，您将看到一个黑色图像或视频。
