我正在将 APNS 集成到我的 iPhone 应用程序中。我已经浏览了 Apple 提供的 Apple Push Notification 文档。我对服务器端有疑问。请在下面找到我的疑问，

  1. Apple said to create a server from below steps,

    Installing the SSL Certificate and Key on the Server:
    You should install the SSL distribution certificate and private cryptographic key you obtained earlier on the server computer on which the provider code runs and from which it connects with the sandbox or production versions of APNs. To do so, complete the following steps:
    1.1.Open Keychain Access utility and click the My Certificates category in the left pane.
    1.2.Find the certificate you want to install and disclose its contents.
    You'll see both a certificate and a private key.
    1.3.Select both the certificate and key, choose File > Export Items, and export them as a Personal Information Exchange (.p12) file.
    1.4.Servers implemented in languages such as Ruby and Perl often are better able to deal with certificates in the Personal Information Exchange format. To convert the certificate to this format, complete the following steps:
         a.In KeyChain Access, select the certificate and choose File > Export Items. Select the Personal Information Exchange (.p12) option, select a save location, and click Save.
         b.Launch the Terminal application and enter the following command after the prompt: openssl pkcs12 -in CertificateName.p12 -out CertificateName.pem -nodes
    1.5.Copy the .pem certificate to the new computer and install it in the appropriate place.

Am clear to create a server (i assume it will be .php server). Am doubt is how we storing all user's DeviceTokens in the server?

2. How to send push notifications to all registered devicetokens?
3. How to send push notifications to a specific user?

您能否就我的问题提出一些建议？我从此链接获得了一个示例 .php 文件http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12。请帮我。提前致谢。

您可以使用以下代码在服务器端获取它：

-(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSLog(@"My token is: %@", deviceToken);


    NSData *postData = [[NSString stringWithFormat:@"token=%@", deviceToken] dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"YOURDOMAIN/FILE.php"]]];

    [request setHTTPMethod:@"POST"];

    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];

    [request setHTTPBody:postData];

    NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
}

只需将您的令牌存储在数据库中（$_POST['token']）

要发送通知，您必须执行如下所示的循环：

//getTokens from database
$deviceToken = getDeviceTokens();

foreach($arr AS $key => $val)
    {
        // Create the payload body
        $body['aps'] = array(
                'alert' => 'Puuuuush',
                'sound' => 'vuvzela.wav',
                'badge' => ($badge != (null) ? $badge + 1 : 1)
                );

// Encode the payload as JSON
        $payload = json_encode($body);

        // Build the binary notification
        $msg = chr(0) . pack('n', 32) . pack('H*', $val) . pack('n', strlen($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;

        $count++;
    }

您需要将所有设备令牌存储在您的服务器中。您必须为此设置一个数据库。要发送推送通知，您需要将消息和设备令牌信息从您的服务器发送到 APNS。

如果您想向特定用户发送推送通知，您的应用程序应将用户信息与设备令牌一起发送到您的服务器。并且您需要将用户信息和设备令牌保存在数据库中。如果您需要向特定用户发送通知，请获取该用户的设备令牌，形成消息并将其发送到 APNS。

您引用的两部分教程包含所有这些详细信息。它有一个可下载的 php 脚本供您试用。
