知道用户何时从我的应用程序“读取”推送通知吗？

Question

当用户从我的应用中读取或“看到”了推送通知时，是否可以获取回调或其他通知？

Answer 1

You get a callback only if the user taps on the notification to open the app. In that case either didReceiveRemoteNotification (if app was active or in the background) or application:didFinishLaunchingWithOptions (if app wasn't running) is called. In both of them you can access the dictionary containing the push notification data, and callback your server if you wish.
