在后台问题苹果推送通知 [英] Apple Push Notification in Background Issue

问题描述

我用parse.com作为我的APN供应商的测试程序，我要建。我已经证实了推送通知的工作，我已经能够成功地接收警报时，应用程序是在前台。另外，我在我的plist指定的 UIBackgroundModes 键远程通知值。

在我的应用程序，我想收到推送通知时，向用户发送当前位置的数据传回我的应用程序特定的parse.com数据库。我并不真正关心的通知有效载荷本身，作为通知只是为了得到一个小片信息的一种手段。该应用程序是不断在后台收集数据并将其存储在一个持久的NSDictionary 。

我已经把在应用程序发送code中的位置：didReceiveRemoteNotification：方法。如果我的应用程序是在前台当我收到通知，该方法被调用。如果我的应用程序在后台，该方法不会被调用。

• 难道我做错了什么？


• 它甚至有可能执行的API请求应用程序：didReceiveRemoteNotification：当应用程序在后台与用户没有与通知**互动

编辑：问题仍然存在，即使当我使用应用程序：didReceiveRemoteNotification：fetchCompletionHandler：

的 注意：我的NSDictionary全位置数据是不是空的。另外，我不试图做任何UI操作在后台 - 只是想执行一个API请求的

解决方案

检查以下内容：

• 的通知有效载荷包括内容提供

  {警告：，
徽章：0
内容提供：1，
声音：}
 

I'm using parse.com as my APNs provider for a test app I'm building. I've confirmed that push notifications are working as I have been able to successfully receive alerts when the app is in the foreground. Also, I have the remote-notification value for the UIBackgroundModes key specified in my plist.

In my app, I'm wanting to send a user's current location data back to my app-specific parse.com database when a push notification is received. I don't actually care about the notification payload itself, as the notification is just a means to getting a small piece of info. The app is constantly collecting data in the background and storing it in a persistent NSDictionary.

I've put the location sending code in the application:didReceiveRemoteNotification: method. If my app is in the foreground when I receive a notification, the method gets called. If my app is in the background, the method isn't called.

• Am I doing something wrong?
• Is it even possible to execute an API request in application:didReceiveRemoteNotification: when the app is in the background and the user hasn't interacted with the notification?**

EDIT: The problem persists even when I use application:didReceiveRemoteNotification:fetchCompletionHandler:.

Note: My NSDictionary full of location data isn't empty. Also, I am not attempting to do any UI manipulation in the background - just trying to perform an API request.

解决方案

Check the following:

• Notification payload includes "content-available"

{"alert":"",
"badge":"0",
"content-available":"1",
"sound":""}
