didReceiveRemoteNotification not getting invoked - objective-c

Question

I am creating app in iOS/android. When a remote notification is received in the device, didReceiveRemoteNotification should get called. But it is not happening. My server side code for sending msg through APNS is as under:
$deviceToken = $obj_listener->ref_id;
// Put your private key's passphrase here:
$passphrase = 'blahblah';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', '/var/www/mobileapp/TestAppCK.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp){
$this->log->debug("Failed to connect: $err $errstr" . PHP_EOL);
exit("Failed to connect: $err $errstr" . PHP_EOL);
}
$badge_count = $obj_listener->badge_count + 1;
// Create the payload body
$body['aps'] = array(
//'alert' => 'Message received',
'sound' => 'default',
'badge' => $badge_count,
'msg_id' => $this->msg_id,
//'user_key' => $obj_listener->ref_id,
'email' => $obj_listener->to_email_id
);
// Encode the payload as JSON
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
// Close the connection to the server
fclose($fp);
My objective-c side code is as under:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
//UIWebView *NewWebView = NULL;
NSLog(#"didReceiveRemoteNotification function");
return;
}
I have checked for the device token in the server side code. It is correct for the device.
Why is the above function not getting called. Thanks in advance.

Answer 1

If you don't register for notifications at your app start, they will never be received.
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)];
Now, about your server side, I suggest you run your code in debug mode and see if Apple's gateway is being properly reached through SSL. A simple bad cert or lack of it can take you away days of work. Personal experience.

If Application is not in background you should use following code
//-------------- check notification when app is come to foreground after apllication get terminated ----------------//
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (localNotif) {
[self handleRemotNotification:[launchOptions valueForKey:#"UIApplicationLaunchOptionsRemoteNotificationKey"]]; // private method
}
