推荐答案

在我看来，您可以使用 NSUserDefaults 来存储用户相关信息.在您的情况下推送通知.然而，只是一个想法，您可以简单地将通知附加到本地存储或用户设备上的 txt 文件，并在用户访问时删除该元素.

In my opinion you can use NSUserDefaults to store user related information. Push Notifications in your case. However, just a thought, you can simple append the notifications to local storage or a txt file on user device and remove the element as user accesses it.

但这仅在用户使用应用程序时有效.如果您希望即使在应用程序不工作时也能正常工作，您需要创建一个后端并将这些数据存储在某种云数据库中.您可以从数据中提取记录，并在再次打开应用程序时再次推送到 NSUserDefaults 或本地 txt 文件.

But this will only work when user is using the app. In case you want to make this work even when the app is not working, you need to make a backend and store these data in some kind of cloud database. You can extract the records from data and push again to NSUserDefaults or local txt file when the app is turned on again.
