# update()

Tells the authorization plug-in to get and display the appropriate view in the authorization plug-in’s user interface.

```
func update()
```

## Discussion

Your subclass of [`SFAuthorizationPluginView`](/documentation/SecurityInterface/SFAuthorizationPluginView) should call this method when a user clicks a button in your view that should result in a new view being displayed. Calling this method causes the authorization plug-in to get the new view and display it.
