Send remote push notification to specific user
<p>I created a code to send remote notification using APNs, I created a development  certificate, ssl, etc. The code worked very well, when I call my php script on my server, the script send a notification and my app on my iPhone show the notification.
But I have a doubt, this is a generic code, so this code will send a nofication to all iphones that has my app, but if I need to send a notification to a specific user? Like whatsapp for example? How can I inform to APNs what user that should receive the notification?</p>
