一句话，你不能即可。您需要向每个令牌发送消息。

不就像电子邮件一样，可以有多个收件人。

连接打开后，您可以发送一堆消息，也就是首选方式（基于Apples SDK）。

您还应该在多个通知中保留与APN的连接。 APN可以考虑快速重复建立的连接，并将其拆除为拒绝服务攻击。出错时，APN会关闭发生错误的连接。

I want to send same messages to all devices who are registered with application but how can send them without making multiple connections...

My current PHP code:

ctx = stream_context_create();  
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');  
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);  
if (!$fp)
{
  print "Failed to connect $err $errstr\n";
  return;
}
$msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
fwrite($fp, $msg);

Bottom line, you can't. You need to send a message to each token.

Its not working like a email where you can have multiple recipients.

Once the connection is open you can send a bunch of messages, thats also the preferred way (based on Apples SDK).

from the SDK:

http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingWIthAPS/CommunicatingWIthAPS.html#//apple_ref/doc/uid/TP40008194-CH101-SW2

You should also retain connections with APNs across multiple notifications. APNs may consider connections that are rapidly and repeatedly established and torn down as a denial-of-service attack. Upon error, APNs closes the connection on which the error occurred.
