```

## Parameters

`title`

The title of the new button.

## Discussion

Adding too many buttons can cause the alert view to scroll. For guidelines on the best ways to use an alert in an app, see [Temporary Views](https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/MobileHIG/Alerts.html#//apple_ref/doc/uid/TP40006556-CH14).
