alertSetting

The authorization status for displaying alerts.

Declaration

@property(readonly, nonatomic) UNNotificationSetting alertSetting;
macOS
@property(readonly, atomic) UNNotificationSetting alertSetting;

Discussion

When the value of this property is UNNotificationSettingEnabled, the app is authorized to display alerts. Authorization does not guarantee that alerts always appear on the user’s screen. When a device is unlocked, the alertStyle property determines the presentation style for the alert, which can include not displaying the alert at all.

The system tries to display an alert when the title, subtitle, or body properties of a UNNotificationContent object contain values, or when the aps dictionary in a remote notification contains the alert key.
