# rotationMode

Determines whether objects animating along the path rotate to match the path tangent.

```
var rotationMode: CAAnimationRotationMode? { get set }
```

## Discussion

The possible values for this property are described in [Rotation Mode Values](/documentation/QuartzCore/rotation-mode-values). The default value of this property is `nil`, which indicates that objects should not rotate to follow the path.

The effect of setting this property to a non-`nil` value when no path object is supplied is undefined.

## See Also

[`path`](/documentation/QuartzCore/CAKeyframeAnimation/path)
