Important:UIUserNotificationCategory is deprecated in iOS 10. Use UNNotificationCategory instead. A UIUserNotificationCategory object encapsulates information about custom actions that your app can perform in response to a local or push notification.
Each instance of UIUserNotificationCategory represents a group of actions to display in conjunction with a single notification. The title of each action is uses as the title of a button in the alert displayed to the user. When the user taps a button, the system reports the selected action to your app delegate.
To display a group of actions for a specific notification, configure the local or push notification with the category name of the group. For local notifications, you specify this name when configuring your UILocalNotification object. For push notifications, your server specifies a group of actions by adding a category key (whose value is the identifier of the group) to the push notification’s payload.
In apps that run in versions of iOS prior to iOS 8, use the UIAlertView class to display an alert message to the user. An alert view functions similar to but differs in appearance from an action sheet (an instance of UIActionSheet).
Important:UILocalNotification is deprecated in iOS 10. Use UNNotificationRequest instead. A UILocalNotification object specifies a notification that an app can schedule for presentation at a specific date and time.
Important:UIMutableUserNotificationCategory is deprecated in iOS 10. Use UNNotificationCategory instead. A UIMutableUserNotificationCategory object encapsulates information about custom actions that your app can perform in response to a local or push notification. Use instances of this class to customize the actions included in an alert when space onscreen is constrained.
Important: UISearchDisplayController is deprecated in iOS 8. (Note that UISearchDisplayDelegate is also deprecated.) To manage the presentation of a search bar and display search results in iOS 8 and later, instead use UISearchController.
The UIStoryboardPopoverSegue class defines a specific type of segue for presenting content in a popover. For popover segues, the destination view controller contains the content to be displayed in the popover. This class provides an additional popoverController property so that your custom code has access to the popover controller object. For example, you might want to store the popover controller elsewhere in your code so that you can dismiss the popover programmatically.
Important:UIUserNotificationAction is deprecated in iOS 10. Use UNNotificationAction instead. A UIUserNotificationAction object represents a custom action that your app can perform in response to a remote or local notification.
Important:UIUserNotificationSettings is deprecated in iOS 10. Use UNNotificationSettings instead. A UIUserNotificationSettings object encapsulates the types of notifications that can be displayed to the user by your app.
