关闭应用程序时如何处理localnetifications

Question

我在这里所有问题中都搜索过，但是没有解决方案。

i使用UserInfo选项安排了LocalNetification。当应用在前景时，通知到达，并且可以使用系统单独调用的此功能完美处理。

• 对于本地通知

  func application(_ application: UIApplication, didReceive notification: UILocalNotification) {
      if application.applicationState == .active {
          return
      }
      //My implementation
  }
  

• 用于远程通知

  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
      if application.applicationState == .active {
          return
      }
      //My implementation
  }
  

，但是问题是，当应用程序关闭时，此功能未调用，我无法处理所需的数据。

我尝试在AppDelegate中的该功能中获取UserInfo：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    if let localUserInfo = launchOptions?[UIApplicationLaunchOptionsKey.localNotification] as? [AnyHashable: Any] {
        // My implementation
    } else if let remoteUserInfo = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [AnyHashable: Any] {
        // My implementation
    }
    return true
}

但是..没有工作...

有人可以帮我吗？

预先感谢。

您是否注册了通知？在didfinishlaunchingwithoptions((中：

    // Register Notifications
            UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge], completionHandler: { granted, error in
                if granted {
                    print("User notifications are allowed")
                } else {
                    print("User notifications are NOT allowed")
                }
            })
            application.registerForRemoteNotification()
            UNUserNotificationCenter.current().delegate = self

然后，您应该在UnusernotificationCenterdelegate方法中捕获本地通知：

extension AppDelegate: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        completionHandler()
    }
}

如果用户单击它是本地还是远程，您都会在didFinishLaunchingWithOptions中获取通知
