# MPMoviePlayerScalingModeDidChangeNotification

Posted when the scaling mode of a movie player has changed. There is no `userInfo` dictionary.

```
extern NSString * const MPMoviePlayerScalingModeDidChangeNotification;
```

## Discussion

Scaling mode can change programmatically or by user interaction. To set or retrieve the scaling mode of a movie player, access its [`scalingMode`](/documentation/MediaPlayer/MPMoviePlayerController/scalingMode) property. The movie player whose state has changed is available as the object associated with the notification.
