环信的推送

今天花了一天的时间，终于将推送给弄出来了，最悲催的是，做完后，才发现真的很容易，步骤如下

1.先创建一个apns证书，链接如下

http://developer.easemob.com/docs/emchat/ios/push/certificate.html

创建完证书后，将证书弄成p12文件，然后上传到环信后台

2.再创建真机调试证书，和描述文件，保证能进行真机调试。并且appid要又推送功能

3.绑定环信证书和appkey

//注册 APNS文件的名字,需要与后台上传证书时的名字一一对应

NSString *apnsCertName = @"chatdemo";

[[EaseMobsharedInstance] registerSDKWithAppKey:@“4545521”apnsCertName:apnsCertName];

[[EaseMobsharedInstance] enableBackgroundReceiveMessage];

[[EaseMobsharedInstance] application:applicationdidFinishLaunchingWithOptions:launchOptions];

    

4.然后实现环信的几个方法

// 收到消息回调

-(void)didReceiveMessage:(EMMessage *)message{

    

#if !TARGET_IPHONE_SIMULATOR

    [selfplaySoundAndVibration];

    

    BOOL isAppActivity = [[UIApplicationsharedApplication] applicationState] ==UIApplicationStateActive;

    if (!isAppActivity) {

        [selfshowNotificationWithMessage:message];

    }

#endif

}

- (void)playSoundAndVibration{

    

    //如果距离上次响铃和震动时间太短,则跳过响铃

    NSLog(@"%@, %@", [NSDatedate], self.lastPlaySoundDate);

    NSTimeInterval timeInterval = [[NSDatedate]

                                   timeIntervalSinceDate:self.lastPlaySoundDate];

    if (timeInterval <kDefaultPlaySoundInterval) {

        return;

    }

    //保存最后一次响铃时间

    self.lastPlaySoundDate = [NSDatedate];

    

    // 收到消息时，播放音频

    [[EaseMobsharedInstance].deviceManagerasyncPlayNewMessageSound];

    // 收到消息时，震动

    [[EaseMobsharedInstance].deviceManagerasyncPlayVibration];

}

- (void)showNotificationWithMessage:(EMMessage *)message{

    id<IEMMessageBody> messageBody = [message.messageBodiesfirstObject];

    NSString *messageStr = nil;

    switch (messageBody.messageBodyType) {

        caseeMessageBodyType_Text:

        {

            messageStr = ((EMTextMessageBody *)messageBody).text;

        }

            break;

        caseeMessageBodyType_Image:

        {

            messageStr = @"[图片]";

        }

            break;

        caseeMessageBodyType_Location:

        {

            messageStr = @"[位置]";

        }

            break;

        caseeMessageBodyType_Voice:

        {

            messageStr = @"[音频]";

        }

            break;

        caseeMessageBodyType_Video:{

            messageStr = @"[视频]";

        }

            break;

        default:

            break;

    }

    

    //发送本地推送

    UILocalNotification *notification = [[UILocalNotificationalloc] init];

    notification.fireDate = [NSDatedate]; //触发通知的时间

    

    NSString *title = message.from;

    if (message.isGroup) {

        NSArray *groupArray = [[EaseMobsharedInstance].chatManager groupList];

        for (EMGroup *groupin groupArray) {

            if ([group.groupIdisEqualToString:message.conversation.chatter]) {

                title = [NSString stringWithFormat:@"%@(%@)", message.groupSenderName, group.groupSubject];

                break;

            }

        }

    }

    

    notification.alertBody = [NSStringstringWithFormat:@"%@:%@", title, messageStr];

    notification.alertAction = @"打开";

    notification.timeZone = [NSTimeZonedefaultTimeZone];

    notification.soundName =UILocalNotificationDefaultSoundName;

    //发送通知

    [[UIApplicationsharedApplication] scheduleLocalNotification:notification];

    UIApplication *application = [UIApplicationsharedApplication];

    application.applicationIconBadgeNumber +=1;

}

这样就可以进行消息推送了
