快速ios检查是否显示本地通知

Question

我需要从锁定屏幕获取本地通知数据，否则应用被杀死。有没有一种方法可以检测到它，或者有任何在显示后触发的处理程序？ 我尝试使用当前的UNUserNotificationCenter和UNUserNotificationCenter didReceive，但仍然无法正常工作。

Answer 1

response.notification.request.content.userInfo包含通知数据

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    completionHandler()
    guard let bodyText = response.notification.request.content.userInfo["body"] as? String else {return}
    }

Answer 2

func application(_ application: UIApplication, didReceiveRemoteNotification 
                  userInfo: [AnyHashable : Any])
{

   if application.applicationState == .inactive || application.applicationState == .background 
   {
      //opened from a push notification when the app was on background
   }
}
