# viewDidAppear()

Called when the title bar accessory view controller’s view is fully transitioned onto the screen.

## Declaration

```swift
func viewDidAppear()
```

## Discussion

Discussion This method is called after the completion of all drawing and animations involved in the initial appearance of the accessory view. You can override this method to perform tasks appropriate for that time—such as work that should not interfere with the presentation animation, or starting an animation that you want to begin after the view appears—but you must call super in your implementation.
