# isFullscreen

A Boolean that indicates whether the movie player is in full-screen mode.

```
var isFullscreen: Bool { get set }
```

## Discussion

The default value of this property is <doc://com.apple.documentation/documentation/Swift/false>. Changing the value of this property causes the movie player to enter or exit full-screen mode immediately. If you want to animate the transition to full-screen mode, use the [`setFullscreen(_:animated:)`](/documentation/MediaPlayer/MPMoviePlayerController/setFullscreen(_:animated:)) method instead.

Whenever the movie player enters or exits full-screen mode, it posts appropriate notifications to reflect the change. For example, upon entering full-screen mode, it posts [`MPMoviePlayerWillEnterFullscreenNotification`](/documentation/MediaPlayer/MPMoviePlayerWillEnterFullscreenNotification) and [`MPMoviePlayerDidEnterFullscreenNotification`](/documentation/MediaPlayer/MPMoviePlayerDidEnterFullscreenNotification) notifications. Upon exiting from full-screen mode, it posts [`MPMoviePlayerWillExitFullscreenNotification`](/documentation/MediaPlayer/MPMoviePlayerWillExitFullscreenNotification) and [`MPMoviePlayerDidExitFullscreenNotification`](/documentation/MediaPlayer/MPMoviePlayerDidExitFullscreenNotification) notifications.

The value of this property may also change as a result of the user interacting with the movie player controls.
