找到存在然后发送推送通知

Question

I am using Openfire for the xmpp server and so far its been great. The problem I am facing now is with push notifications. The app is written in Xcode which gets user data from a PHP Api. Openfire is the xmpp server. The issue is that when the app sends a message to openfire I would need to also query the Php api to see if the user is online and if they are not, send a push notification. This would have to happen for each message sent and as you might guess that will affect performance with all those requests happening.

I have everything working, I just cant get past this hump. If only openfire would fife off a request of my choice upon receiving a message.

Can anyone suggest a better idea? Basically need to know if the user is online (presence) before so that I know to fire off the push notification.

One thing also for sending push notification php script is right or openfire have some plugin.

Thanks.

I think using php script to check for offline user is an expensive affair.

I have used ejabberd server. For which you can create custom modules using "offline_message_hook" and using this module you can invoke php script to send push notification.

This hook is called when someone send message to an offline user. Following link might be helpful.
