iPhone应用中APNS推送通知流程代码实现案例

iPhone应用中APNS推送通知流程代码实现案例是本文要介绍的内容，主要是如何来实现APNS的推送通知，具体内容来看本文详细代码。

1. 将app注册notification里面, 并从APNS上获取测试机的deviceToken.

1. - (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions {

2. [[UIApplication sharedApplication] registerForRemoteNotificationTypesUIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

3. // other codes here.

4. return YES;

5. }

6.

7. - (void)applicationUIApplication *)application didRegisterForRemoteNotificationsWithDeviceTokenNSData *)deviceToken {

8. NSLog(@"deviceToken: %@", deviceToken);

9. }

10.

11. - (void)applicationUIApplication *)application didFailToRegisterForRemoteNotificationsWithErrorNSError *)error {

12. NSLog(@"Error in registration. Error: %@", error);

13. }

14.

15. - (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)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. }

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

2. 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 $errstrn";

28. return;

29. }

30. else {

31. print "Connection OKn<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。
