如何在同一时间和同一个应用程序中集成多个推送通知

I just want to know is it possible to integrate multiple push notifications which fire at the same time & that is for the same time.

For example,

In skype if someone has texted me for the 5 times all 5 texts will be shown to me as a notification.

How this can be done with ios. How to handle this? This can be done from client side or server side?

Any help is appreciated !!
