UIAlertView

UIAlertView was a class in Apple's UIKit framework used to display alert messages to the user. It provided a simple way to present information or ask for user confirmation within an application. An alert view typically consisted of a title, a message, and one or more buttons. The buttons allowed the user to interact with the alert, such as dismissing it or performing a specific action.

UIAlertView was commonly used for tasks like notifying the user of an error, confirming a destructive action (like deleting data), or requesting simple input. It was modal, meaning the user had to dismiss the alert before they could interact with the rest of the application's interface. Developers could customize the alert's appearance to some extent and define the behavior associated with each button.

It's important to note that UIAlertView has been deprecated by Apple. In modern iOS development, developers are encouraged to use UIAlertController instead. UIAlertController offers more flexibility in terms of presentation styles, including action sheets and alerts, and provides a more modern and adaptable API for handling user notifications and interactions.
