# backAction

The back action for the navigation bar.

## Declaration

```swift
@NSCopying var backAction: UIAction? { get set }
```

## Discussion

Discussion If a back button already appears in the navigation bar, setting this property replaces its action without modifying its appearance. Otherwise, setting this property generates a back button with the image or title from the action you specify, unless you use the UINavigationItem.ItemStyle.editor navigation style.
