pass new post title, link to other server ?

dear developers,

i’ve developed a Rss app on the iOS Platfotm, it works perfectly, i’ve been fetching title, links, thumbnail from my wordpress , i added push notifications support for my app , but i need to integrate my wordpress to the push notifications server, that i can send the new title and link as my alert

can anyone point me where i should embed my code , and what are the variable names i should be looking for :

here is the code am trying to implement :

// Push The notification with parameters
$this->load->library('PushBots');
$pb = new PushBots();
// Application ID
$appID = 'xxxxxxxxxx';
// Application Secret
$appSecret = 'xxxxxxxxxx';
$pb->App($appID, $appSecret);

// Notification Settings
$pb->Alert($msg);
$pb->Sound($sound);
$pb->Badge($badge);
$pb->Platform($platforms);

// Tags Array
$pb->Tags($tags);

// Custom fields
$pb->Payload($customfields);

// Country or state
$pb->Geo($country , $gov);

// Push it !
$pb->Push();

i just need the post title, and link in assigned to the variables $name, $customfields

thank you in advance
