# currentThumbImage

The thumb image currently being used to render the slider.

```
var currentThumbImage: UIImage? { get }
```

## Discussion

Sliders can have different thumb images for different control states. The active control state determines which thumb image is stored in this property. To get the thumb image for a different control state, use the [`thumbImage(for:)`](/documentation/UIKit/UISlider/thumbImage(for:)) method.

If no custom thumb images have been set using the [`setThumbImage(_:for:)`](/documentation/UIKit/UISlider/setThumbImage(_:for:)) method, this property is `nil`. In that situation, the slider uses the default thumb image for drawing.
