title: iOS7 Silent Push notification not working
body: <p>I have implement push notifications in iOS7. As iOS7 having features of receiving push notification silently by using method</p>
  
  <pre><code>- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo performFetchWithCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler
  {
  }
  </code></pre>
  
  <p>But this method never getting called as I am sending notification. I am receiving the notification in notification tray But notification should not be there as It is silent. I am using Raywenderlich's PHP code to send the push Notification. I have added content-available key also like this</p>
  
  <pre><code>// Create the payload body
  
  $body['aps'] = array(
      'content-available' =&gt; '1',
      'alert' =&gt; $message,
      'sound' =&gt; 'default'
      );
  </code></pre>
  
  <p>Please Help!!!</p>
