前言
本文大部分参考 iOS利用voip push实现类似微信(QQ)电话连续响铃效果 有兴趣的可以多参考它下
自己代码：gitHubDemo
最近客户要求需要做出类似微信的 视频拉起的呼叫的功能，开始使用的是mqtt的方式来发起的消息拉起，
结果：发现 app退到后台、或者app杀死了，就不会收到了（也就拉起不了了）
试了：APNs的方式,结果APNs根本实现不了连续通知，而且它也不会实现像本地通知那样会有连续响铃的效果（微信一般大概30s左右）
为了实现类似微信的方式，最终：我们通过 voip的方式来实现app的视频的拉起
-
说明
- VoIP 推送基于pushKit框架
- 好处：
- 只有当VoIP发生推送时，设备才会唤醒，从而节省能源。
- VoIP推送被认为是高优先级通知，并且毫无延迟地传送。
- VoIP推送可以包括比标准推送通知提供的数据更多的数据。
- 如果收到VoIP推送时，您的应用程序未运行，则会自动重新启动。
- 即使您的应用在后台运行，您的应用也会在运行时处理推送。
-
voip的集成
- 在Xcode中开启VoIP推送
voip_01.jpeg
-
在Apple Developer创建VoIP证书
voip_02.jpeg
-
跟APNs证书不同，VoIP证书不区分开发和生产环境，VoIP证书只有一个，生产和开发都可用同一个证书。另外有自己做过推送的应该都知道服务器一般集成的.pem格式的证书，所以还需将证书转成.pem格式，后面会介绍怎么转换.pem证书。
导入framework:PushKit.framework -
Objective-C代码集成，导入头文件.
#import <PushKit/PushKit.h> -
设置代理
PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()]; pushRegistry.delegate = self; pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP]; -
代理方法
//应用启动此代理方法会返回设备Token 、一般在此将token上传服务器 - (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{ } //当VoIP推送过来会调用此方法，一般在这里调起本地通知实现连续响铃、接收视频呼叫请求等操作 - (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type { }

--------------------------------------------------
使用：
在appdelegate.m里面
导入 #import "TalkVideoManager.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
......
//配置voIP
[[TalkVideoManager sharedClient] initWithSever];
return YES;
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
NSLog(@"点击了本地通知进来了---%@",notification.userInfo);
[[TalkVideoManager sharedClient] cancleCall];
.......//处理数据
}
说白了：就是通过voip发的消息回调，来进行发送本地通知，然后点击本地通知，再做相应的数据逻辑处理。
-
建立本地测试环境(自己搭建一个简单的测试环境先测试通，然后再与服务器对接)
-
制作.pem格式证书
1、将之前生成的voip.cer SSL证书双击导入钥匙串 2、打开钥匙串访问，在证书中找到对应voip.cer生成的证书，右键导出并选择.p12格式,这里我们命名为voippush.p12,这里导出需要输入密码(随意输入，别忘记了)。 3、目前我们有两个文件，voip.cer SSL证书和voippush.p12私钥，新建文件夹命名为VoIP、并保存两个文件到VoIP文件夹。 4、把.cer的SSL证书转换为.pem文件，打开终端命令行cd到VoIP文件夹、执行以下命令 openssl x509 -in voip.cer -inform der -out VoiPCert.pem 5、把.p12私钥转换成.pem文件，执行以下命令（这里需要输入之前导出设置的密码） openssl pkcs12 -nocerts -out VoIPKey.pem -in voippush.p12 6、再把生成的两个.pem整合到一个.pem文件中 cat VoiPCert.pem VoIPKey.pem > ck.pem 最终生成的ck.pem文件一般就是服务器用来推送的。 -
新建php文件（保存名字为push.php）
<?php // Put your device token here (without spaces): $deviceToken = '这里填写手机注册的devideToken'; $passphrase = '这里填写导出p12文件的密码'; // Put your alert message here: $message = '要推送的内容'; $info = array("id"=>"1","address"=>"IANA"); //自己写的一个info字典（自己后台可以自定义） //////////////////////////////////////////////////////////////////////////////// $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem'); //这里的ck.pem需要和导出的证书名字要一致 stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); stream_context_set_option($ctx, 'ssl', 'verify_peer', false); // Open a connection to the APNS server //ssl://gateway.sandbox.push.apple.com:2195（测试环境） //ssl://gateway.push.apple.com:2195（生产环境） $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err,$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to APNS' . PHP_EOL; // Create the payload body $body['aps'] = array( 'content-available' => '1', 'alert' => $message, 'sound' => 'weixin.m4a', 'badge' => 0, 'info'=> $info, ); // Encode the payload as JSON $payload = json_encode($body); // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Message not delivered' . PHP_EOL; else echo 'Message successfully delivered' . PHP_EOL; // Close the connection to the server fclose($fp); ?> -
推送测试
-
将ck.pem 文件和push.php 放在同一个文件夹下（必须）
-
一般测试VoIP推送的稳定性最好是通过Hoc证书打包在生产环境中测试
-
打开terminal ，cd到 push.php 文件目录下
-
输入：php push.php (不出意外就可以收到推送啦)

补充点（摘录 iOS利用voip push实现类似微信(QQ)电话连续响铃效果）
- 当app要上传App Store时，请在iTunes connect上传页面右下角备注中填写你用到VoIP推送的原因，附加上音视频呼叫用到VoIP推送功能的demo演示链接，演示demo必须提供呼出和呼入功能，demo我一般上传到优酷。
- 经过大量测试，VoIP当应用被杀死（双击划掉）并且黑屏大部分情况都能收到推送，很小的情况会收不到推送消息，经测试可能跟手机电量消耗还有信号强弱有关。 再强调一遍，测试稳定性请在生产环境测试。
