环信透传

1、发透传消息

//通过透传发送当前位置信息给领导

EMChatCommand*shareCommand = [[EMChatCommandalloc]init];

shareCommand.cmd=@"ResponseLocation";//当前cmd消息的关键字

EMCommandMessageBody*shareMsgBody = [[EMCommandMessageBodyalloc]initWithChatObject:shareCommand];

//设置要发给谁,fromToken是环信用户username或者群聊groupid

EMMessage*shareMsg = [[EMMessagealloc]initWithReceiver:_fromTokenbodies:@[shareMsgBody]];

shareMsg.messageType=eMessageTypeChat;//单聊或者群聊

//latitude,longitude:获取到的经纬度

shareMsg.ext=@{

@"latitude":[NSStringstringWithFormat:@"%f",lat],

@"longitude":[NSStringstringWithFormat:@"%f",lng],

@"reporttime":_reporttime,

@"track":@""

};

[[EaseMobsharedInstance].chatManagerasyncSendMessage:shareMsgprogress:nil];

2、接收透传消息

-(void)didReceiveCmdMessage:(EMMessage*)cmdMessage{

EMCommandMessageBody*body = cmdMessage.messageBodies.firstObject;

//接收员工的即时位置信息

if([body.actionisEqualToString:@"ResponseLocation"]) {

NSString*latitude = [cmdMessage.extobjectForKey:@"latitude"];

NSString*longitude = [cmdMessage.extobjectForKey:@"longitude"];

NSString*reporttime = [cmdMessage.extobjectForKey:@"reporttime"];

NSMutableDictionary*locationInfo = [[NSMutableDictionaryalloc]init];

[locationInfosetObject:latitudeforKey:@"lat"];

[locationInfosetObject:longitudeforKey:@"lng"];

[locationInfosetObject:reporttimeforKey:@"reporttime"];

[[NSNotificationCenterdefaultCenter]postNotificationName:@"userLocationNotification"object:niluserInfo:locationInfo];

}

}

3、配置

若想APP在后台时也使用，要在环信后台配置ios证书
