适用于iOS应用的后台主题推送通知

Question

I was trying to implement GCM in iOS app. I encountered problem when I wanted to send topic specific messages. It's working without problem when app is in foreground but I'm not able to receive any messages while app is in the background. Is there any specific setting or GCM message content that need to be used to make it possible? Is the possibility to send push notification to all app users that will receive notification even if application will be in the background?

正如ztan所指出的，您要么需要发送用户可见的通知 ，要么使用content_available 。
