推送通知消息未显示在设备中

我指的是本教程 http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1..当它运行此代码时，它显示已成功传递，但消息未出现在设备上。 我完成了APNS的步骤，

这是我尝试过的，我错在哪里？

PHP代码 ：

<?php
// Put your device token here (without spaces):
$deviceToken = 'Device Token';
// Put your private key's passphrase here:
$passphrase = 'pushchat';
// Put your alert message here:
$message = 'My first push notification!';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.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)
  exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
$body['aps'] = array(
    'alert' => $message,
    'sound' => 'default'
 );
 // 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));
if (!$result)
   echo 'Message not delivered' . PHP_EOL;
else
   echo 'Message successfully delivered' . PHP_EOL;
// Close the connection to the server
fclose($fp);
