# rotate(byDegrees:)

Rotates the view’s bounds rectangle by a specified degree value around the origin of the coordinate system, (0.0, 0.0).

```
func rotate(byDegrees angle: CGFloat)
```

## Parameters

`angle`

A `float` value specifying the angle of rotation, in degrees.

## Discussion

See the [`boundsRotation`](/documentation/AppKit/NSView/boundsRotation) method description for more information. This method neither redisplays the view nor marks it as needing display. You must do this yourself by calling the [`display()`](/documentation/AppKit/NSView/display()) method or setting the [`needsDisplay`](/documentation/AppKit/NSView/needsDisplay) property.

This method posts an [`boundsDidChangeNotification`](/documentation/AppKit/NSView/boundsDidChangeNotification) to the default notification center if the view is configured to do so.

## See Also

[`frameRotation`](/documentation/AppKit/NSView/frameRotation)

The angle of rotation, measured in degrees, applied to the view’s frame rectangle relative to its superview’s coordinate system.

[`postsBoundsChangedNotifications`](/documentation/AppKit/NSView/postsBoundsChangedNotifications)

A Boolean value indicating whether the view posts notifications when its bounds rectangle changes.
