# barMinimizeBehavior

The minimize behavior for the navigation bar.

## Declaration

```swift
var barMinimizeBehavior: UIBarMinimizeBehavior { get set }
```

## Discussion

Discussion The default value is UIBarMinimizeBehavior.automatic. When the navigation bar minimizes, an integrated top tab bar will also minimize. By default, the safe area adjusts as the navigation bar minimizes. Use barMinimizationSafeAreaAdjustment to customize this.
