1. 将app注册notification里面, 并从APNS上获取测试机的deviceToken.    
  1. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {        
  2.     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];  
  3.         // other codes here.    
  4.     return YES;
  5. }
  6.  
  7. - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
  8.     NSLog(@"deviceToken: %@", deviceToken);
  9. }
  10.  
  11. - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
  12.     NSLog(@"Error in registration. Error: %@", error);
  13. }
  14.  
  15. - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
  16. {
  17.     
  18.     NSLog(@" 收到推送消息 : %@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
  19.     if ([[userInfo objectForKey:@"aps"] objectForKey:@"alert"]!=NULL) {
  20.         UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"推送通知"
  21.                                                         message:[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]
  22.                                                        delegate:self
  23.                                               cancelButtonTitle:@" 关闭"
  24.                                               otherButtonTitles:@" 更新状态",nil];
  25.         [alert show];
  26.         [alert release];
  27.     }
  28. }
  29.  

启动程序,将app注册到通知项后,在console里面找到打印的deviceToken:
  1. deviceToken: <6974ac11 870e09fa 00e2238e 8cfafc7d 2052e342 182f5b57 fabca445 42b72e1b>


2. 生成app在服务端需要的许可证
1)进入Provisioning Portal, 下载Certificates在development下的证书。
2) 找到需要测试的app id,然后enable它在development下的Apple Push Notification service: Development Push SSL Certificate。需要输入1)中的签名证书才可以生成一个aps_developer_identity.cer.
3) 双击aps_developer_identity.cer,会打开系统的key chain. 在My certificates下找到Apple Development Push Services。需要为certificate和它之下的private key各自export出一个.p12文件。(会出现设置密码过程)
4)需要将上面的2个.p12文件转成.pem格式:
  1. openssl pkcs12 -clcerts -nokeys -out cert.pem -in cert.p12

  1. openssl pkcs12 -nocerts -out key.pem -in key.p12

5)如果需要对 key不进行加密:
  
  1. openssl rsa -in key.pem -out key.unencrypted.pem

6)然后就可以 合并两个.pem文件, 这个ck.pem就是服务端需要的证书了。
  
  1. cat cert.pem key.unencrypted.pem > ck.pem


3. 服务端push通知到ANPS. 在cocoachina找到了两种方法:
  1)php驱动。需要将ck.pem和php脚本放到server 上。全部的php代码是:
    
  1. <?php
  2. $deviceToken = '6974ac11 870e09fa 00e2238e 8cfafc7d 2052e342 182f5b57 fabca445 42b72e1b';
  3. $pass = '123456';   // Passphrase for the private key (ck.pem file)
  4.  
  5. // Get the parameters from http get or from command line
  6. $message = $_GET['message'] or $message = $argv[1] or $message = 'A test message from worldcup';
  7. $badge = (int)$_GET['badge'] or $badge = (int)$argv[2];
  8. $sound = $_GET['sound'] or $sound = $argv[3];
  9.  
  10. // Construct the notification payload
  11. $body = array();
  12. $body['aps'] = array('alert' => $message);
  13. if ($badge)
  14.   $body['aps']['badge'] = $badge;
  15. if ($sound)
  16.   $body['aps']['sound'] = $sound;
  17.  
  18. /* End of Configurable Items */
  19. $ctx = stream_context_create();
  20. stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');  
  21. // assume the private key passphase was removed.
  22. stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);
  23.  
  24. // connect to apns
  25. $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
  26. if (!$fp) {
  27.     print "Failed to connect $err $errstr\n";
  28.     return;
  29. }
  30. else {
  31.    print "Connection OK\n<br/>";
  32. }
  33.  
  34. // send message
  35. $payload = json_encode($body);
  36. $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
  37. print "Sending message :" . $payload . "\n";  
  38. fwrite($fp, $msg);
  39. fclose($fp);
  40. ?>

请 求一次 http://127.0.0.1/apns/apns.php?message=A%20test%20message%20from%20localhost&badge=2&sound=received5.caf就 会向APNS进行一次推送。我的请求结果如下:
  1. Connection OK
  2. Sending message :{"aps":{"alert":"A test message from localhost","badge":2,"sound":"received5.caf"}}


  2)pushMeBaby 驱动。将aps_developer_identity.cer导入到project里面,改名为apns.cer。
 
通过定时器将数据推送给表格,实现数据刷新的

以下代码由 CocoaChina 会员“zhangnan522”分享,主要实现数据定时推送,在表格里自动更新的功能。
