# fullScreenAccessoryViewMinHeight

The minimum height of the toolbar’s full screen accessory view.

## Declaration

```swift
var fullScreenAccessoryViewMinHeight: CGFloat { get set }
```

## Discussion

Discussion The fullScreenAccessoryViewMinHeight is used when the menu bar is hidden. During the reveal, the toolbar’s accessory view’s frame is interpolated between its fullScreenAccessoryViewMinHeight and fullScreenAccessoryViewMaxHeight. If the minimum height is 0 the accessory view isn’t resized; instead a special transition is used to reveal it with the menu bar. This simplifies the accessory view’s task, because it doesn’t have to handle the case of the height being set to 0. To create a fixed-height accessory view, set the fullScreenAccessoryViewMaxHeight and fullScreenAccessoryViewMinHeight properties to be equal. The default value is 0.
