# isTranslucent

A Boolean value that indicates whether the toolbar is translucent.

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

## Discussion

When the toolbar is translucent, configure the [`edgesForExtendedLayout`](/documentation/UIKit/UIViewController/edgesForExtendedLayout) and [`extendedLayoutIncludesOpaqueBars`](/documentation/UIKit/UIViewController/extendedLayoutIncludesOpaqueBars) properties of your view controller to display your content underneath the toolbar.

If the toolbar doesn’t have a custom background image, or if any pixel of the background image has an alpha value of less than `1.0`, the default value of this property is <doc://com.apple.documentation/documentation/Swift/true>. If the background image is completely opaque, the default value of this property is <doc://com.apple.documentation/documentation/Swift/false>. If you set this property to <doc://com.apple.documentation/documentation/Swift/true> and the custom background image is completely opaque, UIKit applies a system-defined opacity of less than `1.0` to the image. If you set this property to <doc://com.apple.documentation/documentation/Swift/false> and the background image isn’t opaque, UIKit adds an opaque backdrop.
