title: Using apple push notification in my application in Detail?
body: <p>How can I use APN in my app?</p>
  
  <p>I need to make my application using the APN. I need all the steps needed like is there another registration with apple for the certificates and how to make the push notification to all the devices that used my app downloaded from the store.</p>
  
  <p>How should I implement the server side from which I will send the message?</p>
  
  <p>I have already implemented this in my app:</p>
  
  <pre><code>[[UIApplication sharedApplication] 
   registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | 
                                      UIRemoteNotificationTypeBadge | 
                                      UIRemoteNotificationTypeSound];
  </code></pre>
