GCM推送通知时，iOS应用程序是在后台 [英] GCM push notification when iOS app is in the background

问题描述

我试图发送推送通知到我的iOS应用程序与GCM。该应用程序不会得到通知时，它的背景，但是当它在前台它。我是用PHP脚本还直接将消息发送到APNS测试推送通知和它的工作背景。

发送到GCM的JSON（我是从一个REST客户端测试其发送）

  {
  要：令牌......
  通知：{
    头衔：GCM TITLE
    身：从GCM
    徽章：1
    声音：默认
  }
}
 

不工作：
从GCM收到didReceiveRemoteNotification的用户信息：

 收到通知：[APS：{
    警报= {
        身体=从GCM
        标题=GCM TILE
    };
    徽章= 1;
    听起来=默认值;
}，gcm.message_id：123 ...]
 

工作：
该用户信息收到PHP脚本时发送（我还添加了与Message_ID到JSON，看是否这就是问题所在）

 收到通知：[APS：{
    警报= {
        身体=从PHP;
        标题=PHP TITLE
    };
    徽章= 2;
    听起来=默认值;
}，gcm.message_id：123 ...]
 

我尝试添加content_available的JSON用不同的组合，但没有帮忙，Content-Type和授权请求报头也被设置：

 内容类型：应用程序/ JSON
授权：关键= ...
 

解决方案

在情况下，如果有人有相同的问题，解决的办法是我的优先级补充说：高到JSON。这样，我得到通知的背景。

  {
  要：令牌......
  优先级：高，
  通知：{
    头衔：GCM TITLE
    身：从GCM
    徽章：1
    声音：默认
  }
}
 

I'm trying to send push notifications to my iOS app with GCM. The app doesn't get the notification when it's in the background but it does when it's in the foreground. I was testing the push notifications with a PHP script also which sends the message directly to the APNS and it's working in the background.

The JSON sent to GCM: (I'm sending it from a rest client for testing)

{
  "to" : "token...",
  "notification" : {
    "title": "GCM TITLE",
    "body" : "FROM GCM",
    "badge": "1",
    "sound": "default"
  }
}

Not working: The userInfo received from GCM in didReceiveRemoteNotification:

Notification received: [aps: {
    alert =     {
        body = "FROM GCM";
        title = "GCM TILE";
    };
    badge = 1;
    sound = default;
}, gcm.message_id: 123...]

Working: The userInfo received when sent from the PHP script (I also added the message_id to the JSON to see if that's the problem)

Notification received: [aps: {
    alert =     {
        body = "FROM PHP";
        title = "PHP TITLE";
    };
    badge = 2;
    sound = default;
}, gcm.message_id: 123...]

I tried adding content_available to the JSON with different combinations but didn't help, the Content-Type and Authorization request headers are also set:

Content-Type:application/json
Authorization:key=... 

解决方案

In case if someone has the same problem, the solution was for me to add the "priority": "high" to the JSON. This way I get the notifications in the background.

{
  "to" : "token...",
  "priority": "high",
  "notification" : {
    "title": "GCM TITLE",
    "body" : "FROM GCM",
    "badge": "1",
    "sound": "default"
  }
}
