# action

The action method to call when someone clicks on the toolbar item.

## Declaration

```swift
var action: Selector? { get set }
```

## Discussion

Discussion If you assign a custom view to the toolbar item, modifying this property updates the action property of the view or calls the setAction: method, if one of them exists. If the item doesn’t contain a custom view, the toolbar item manages the action directly.
