Implementing Push notifications for iOS (Server Side)
提问by Alex1987
We want to be able to push simple text messages to ALL our iphone users. For that we obviously need to create a server side code that stores the device tokens and pushes the messages whenever necessary. Is there any good example on doing this? (Talking about the server code)
我们希望能够向所有 iphone 用户推送简单的短信。为此，我们显然需要创建一个服务器端代码来存储设备令牌并在必要时推送消息。有没有这样做的好例子？（说到服务器代码）
Thanks

Have a look at easyAPNSif you want to host it yourself, or visit Urban Airshipif you are ok with a hosting service (they have an extensive set of documentation)
如果您想自己托管，请查看easyAPNS，如果您对托管服务没问题，请访问Urban Airship（他们有大量文档）
Another good site for info is Ray Wenderlich's site which hosts a 2 part tutorial:

// Push Notification code for IPHONE in PHP
$deviceToken = $users_rows['gcm_regid'];
$passphrase = 'pass1234';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'DrinksterDevelopment.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 120, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;

I also recommend using an external service for that such as Urban Airship or PushApps. I more familiar with the last, and I can tell you that besides of "regular" push notifications messages, you also get messaging by segmentation, location or even scheduling notification. It may not seem like a critical features for you at first, but as your user base grow, you'll see how important those features are.
我还建议为此使用外部服务，例如 Urban Airship 或PushApps。我对最后一个比较熟悉，我可以告诉你，除了“常规”推送通知消息之外，你还可以通过分段、位置甚至调度通知来获取消息。乍一看，这对您来说似乎不是一个关键功能，但是随着您的用户群的增长，您会发现这些功能有多么重要。
