iOS7 Silent Push notification not working

Question

I have implement push notifications in iOS7. As iOS7 having features of receiving push notification silently by using method

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo performFetchWithCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler
{
}

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

// Create the payload body

$body['aps'] = array(
    'content-available' => '1',
    'alert' => $message,
    'sound' => 'default'
    );

Please Help!!!

Answer 1

You should not add 'alert' param in your payload if you want to silent push notification.

pass your param like this.

$body['aps'] = array(
'content-available' => '1'
);

And verify you enabled remote-notification in your project plist.

or

You will get notification by implementing this delegate.

 -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
// Call or write any code necessary to download new data.
completionHandler(UIBackgroundFetchResultNewData);
 }

Answer 2

Try with a integer value :

$body['aps'] = array(
    'content-available' => 1,
    'alert' => $message,
    'sound' => 'default'
    );
