PushKit 占坑

最近项目要做关于voip业务,我们都知道苹果后台是一个假后台,当程序退出到后台时,socket是会断开连接,程序是被挂起的。我们要做的就是类似QQ 微信那种,在程序退到后台时,有电话来时弹出一个通知。要了解pushkit概述请参考下面连接

  • 1.证书创建
    首先创建voip证书

    一步一步往下创建,最后生成下载证书双击安装到钥匙串。
    当安装到钥匙串完成后, 注意:我们还需要另外创建一个配置文件

创建完成后下载 双击安装就行了。

  • 2.接下来上代码
    1. 需要导入push kit框架#import <PushKit/PushKit.h>
    2. 注册通知与pushkit,pushkit要ios8 及以后才可以使用
 if (CurrentSystemVersion.floatValue >= 8.0) {
            UIUserNotificationSettings *userNotifiSetting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:userNotifiSetting];
            PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:nil];
            pushRegistry.delegate = self;
            pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
        }

3.实现代理方法1

- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{
    NSString *str = [NSString stringWithFormat:@"%@",credentials.token];
    _tokenStr = [[[str stringByReplacingOccurrencesOfString:@"<" withString:@""]
                 stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString:@" " withString:@""];
} //这个代理方法是获取了设备的唯tokenStr,是要给服务器的

与apns推送不同,pushjit的token获取跟apnstoken的获取方法不同,apps在

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
    [application registerForRemoteNotifications];//必须先实现这个方法,才会走下面的方法
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    NSLog(@"%@",[[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""]                  stringByReplacingOccurrencesOfString: @">" withString: @""]                 stringByReplacingOccurrencesOfString: @" " withString: @""]);

    NSString *token = [NSString stringWithFormat:@"%@", deviceToken];
    //获取终端设备标识,这个标识需要通过接口发送到服务器端,服务器端推送消息到APNS时需要知道终端的标识,APNS通过注册的终端标识找到终端设备
    NSLog(@"%@",token);
}

获取设备的token,这两个token的值是不同的,注意不要搞混了。

实现代理方法2

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(pancal) name:@"precancel" object:nil];
    NSDictionary *dic = [self jsonToDictionary:[[payload.dictionaryPayload objectForKey:@"aps"] objectForKey:@"alert"]];
    if ([[dic objectForKey:@"cmd"] isEqualToString:@"precall"]) {
        UIUserNotificationType theType = [UIApplication sharedApplication].currentUserNotificationSettings.types;
        if (theType == UIUserNotificationTypeNone)
        {
            UIUserNotificationSettings *userNotifySetting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:userNotifySetting];
        }
        UILocalNotification *backgroudMsg = [[UILocalNotification alloc] init];
        if (backgroudMsg) {
            backgroudMsg.timeZone = [NSTimeZone defaultTimeZone];
            backgroudMsg.alertBody = @"门口机来电";
            backgroudMsg.alertAction = @"查看";
            //设置通知的相关信息,这个很重要,可以添加一些标记性内容,方便以后区分和获取通知的信息
            NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];;
            backgroudMsg.userInfo = infoDic;
            [[UIApplication sharedApplication] presentLocalNotificationNow:backgroudMsg];
            [self cerateAVAudioPlayer];
        }
    }else if ([[dic objectForKey:@"cmd"] isEqualToString:@"precancel"]){
        [[NSNotificationCenter defaultCenter] postNotificationName:@"precancel"
                                                            object:nil];
        [self pancalStopSound];
}

如果一切正常,就算程序杀掉进程,重启,退到后台,服务器推送过来的消息都会走代理方法2,在这里我们可以做一些处理,我这里是弹出了一个本地通知,并且播放提示音效。

使用push kit的优点

1.应用的voip长连接不保持,在收到呼叫或者发起呼叫时再连接;
2.当呼叫发送到voip 服务器时,对端若不在线,通过voip 服务器连接到pushserver向对端发push通知;
3.应用收到voip push通知时,迅速完成注册;
4.呼叫方通过延时操作等逻辑(复杂一点对voip服务器进行改造,被叫连接上来以后通知到主叫侧),再次发起呼叫,通话即成功建立。

java后台服务器搭建

public static void main(String[] args) throws Exception 
{
        try
        {
            //从客户端获取的deviceToken,在此为了测试简单,写固定的一个测试设备标识。
           String deviceToken = "df779eda 73258894 5882ec78 3ac7b254 6ebc66fe fa295924 440d34ad 6505f8c4"
            System.out.println("Push Start deviceToken:" + deviceToken);
            //定义消息模式
            PayLoad payLoad = new PayLoad();
            payLoad.addAlert("this is test!");
            payLoad.addBadge(1);//消息推送标记数,小红圈中显示的数字。
            payLoad.addSound("default");
            //注册deviceToken
            PushNotificationManager pushManager = PushNotificationManager.getInstance();
            pushManager.addDevice("iPhone", deviceToken);
            //连接APNS
            String host = "gateway.sandbox.push.apple.com";
            //String host = "gateway.push.apple.com";
            int port = 2195;
            String certificatePath = "c:/PushTest.p12";//前面生成的用于JAVA后台连接APNS服务的*.p12文件位置
            String certificatePassword = "123456";//p12文件密码。
            pushManager.initializeConnection(host, port, certificatePath, certificatePassword, SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
            //发送推送
            Device client = pushManager.getDevice("iPhone");
            System.out.println("推送消息: " + client.getToken()+"\n"+payLoad.toString() +" ");
            pushManager.sendNotification(client, payLoad);
            //停止连接APNS
            pushManager.stopConnection();
            //删除deviceToken
            pushManager.removeDevice("iPhone");
            System.out.println("Push End");
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
}
}

注意: 用java搭建的后台服务器我们需要提供给服务器.p12文件,用php搭建的服务器我们需要给服务器提供.pem文件

.p12文件导出


DA909015-E4C2-479D-A27B-46E700428C7A.png


右键导出文件即可。

.pem文件导出稍微复杂

pushkit使用就到这里结束了,是不是很简单呢,赶紧来一起愉快玩耍吧。附上使用截图
