# ScreenSaverDefaults

A class that defines a set of methods for saving and restoring user defaults for screen savers.

```
class ScreenSaverDefaults
```

## Overview

[`ScreenSaverDefaults`](/documentation/ScreenSaver/ScreenSaverDefaults) gives you access to preference values you need to configure your screen saver. Because multiple apps can load a screen saver, you can’t use the standard <doc://com.apple.documentation/documentation/Foundation/UserDefaults> object to store preferences. Instead, instantiate this class using the [`init(forModuleWithName:)`](/documentation/ScreenSaver/ScreenSaverDefaults/init(forModuleWithName:)) method, which takes your screen saver’s bundle identifier as a parameter. The resulting object gives you a way to store your preference values and associate them only with your screen saver. Use the inherited <doc://com.apple.documentation/documentation/Foundation/UserDefaults> methods to load, store, or modify values.
