UIActionSheet

UIActionSheet was a class in Apple's UIKit framework for iOS that presented a user with a set of actions. It was typically used for actions related to a specific piece of content or task, such as sharing an item, deleting data, or choosing an option from a list. The action sheet would appear from the bottom of the screen, overlaying the current view, and present a list of buttons representing the available actions. It also had the option to include a destructive action, usually styled in red, and a cancel button to dismiss the sheet.

Developers would configure a UIActionSheet by providing a title, a destructive button title, and a list of other button titles. A delegate object would be assigned to the action sheet to handle the user's selection of a specific action. The delegate method would receive the index of the tapped button, allowing the application to perform the corresponding operation. In addition to direct user interaction, UIActionSheets could also be presented modally or as popovers on iPad.

It's important to note that UIActionSheet has been deprecated since iOS 8. Apple introduced UIAlertController as its successor, which offers a more unified and flexible approach to presenting alerts and action sheets. Developers are strongly encouraged to migrate from UIActionSheet to UIAlertController for new development and for updating existing applications to ensure compatibility with current and future iOS versions. The functionality of UIActionSheet is now encompassed within UIAlertController's `preferredStyle` property when set to `.actionSheet`.
