Description

一种用于直播中更新在线人数的方法及系统 技术领域
本发明涉及互联网移动端应用开发领域，具体涉及一种用于直播中更新在线人数的方法和一种用于直播中更新在线人数的系统。
背景技术
随着科技的快速发展，手机等智能移动设备的功能越发强大，为丰富业余生活，人们经常使用智能移动设备进行直播及观看直播，在移动端的直播过程中，各个直播间存在直播人气的概念，与直播人气相对应为直播间的当前在线人数，某一直播间的当前在线人数越多，说明该直播间越火爆。人气对于用户来说是告知某个直播间是否火爆的重要信息，同时，人气对于主播来说也是一种极大地鼓励。
但是，对于某一个直播间，主播在直播的过程中，用户会进出房间，导致主播间的当前在线人数发生变化，若无法及时对移动端直播软件中直播间的当前在线人数进行实时更新，则直播间会显示一错误的在线人数，从而无法真实反映当前直播间的人气。
发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种用于直播中更新在线人数的方法和一种用于直播中更新在线人数的系统，能够方便快捷的对直播间当前在线人数进行更新。
为达到以上目的，本发明采取的技术方案是：包括：
S1：直播客户端接收弹幕服务器发送的直播间当前在线人数；
S2：直播客户端以代理方式将直播间当前在线人数发送至iOS 系统的视图控制器；
S3：根据获得的直播间当前在线人数，视图控制器以代理方式向子界面抛出更新直播客户端UI的通知，所述子界面为直播客户端UI中显示在线人数的视图界面单元，所述通知的抛出操作在直播客户端的主线程中进行；
S4：子界面获取更新直播客户端UI的通知，进行子界面中在线人数显示的更新。
在上述技术方案的基础上，所述更新直播客户端UI的通知中含有执行代码，所述执行代码用于根据获取的直播间当前在线人数更新子界面中的在线人数显示。
在上述技术方案的基础上，所述更新直播客户端UI的通知为声明函数，所述执行代码位于所述声明函数中，且所述执行代码的执行在直播客户端的主线程中进行。
在上述技术方案的基础上，当更新直播客户端UI的通知抛出后：
S301：判断更新直播客户端UI的通知中是否含有执行代码，若有，转到S402，若没有，则结束；
S302：判断执行代码的执行是否在主线程中进行，若是，转到S4，若不是，则将执行代码的执行操作调回主线程中，然后转到S4。
在上述技术方案的基础上，所述直播客户端与弹幕服务器间基于socket进行通讯。
在上述技术方案的基础上，抛至iOS系统的视图控制器中的直播间当前在线人数，被转化为long long型的数据类型。
在上述技术方案的基础上，所述弹幕服务器按预设时间间隔向直播客户端发送房间人数变化类消息。
本发明还公开了一种用于直播中更新在线人数的系统，包括：
数据接收模块，其用于接收弹幕服务器向直播客户端发送的直播间当前在线人数；
数据传输模块，其用于将数据接收模块接收的直播间当前在线人数抛入iOS系统的视图控制器中，以及控制视图控制器根据获得的直播间当前在线人数向子界面抛出更新直播客户端UI的通知，且所述通知的抛出操作在直播客户端的主线程中进行，所述子界面为直播客户端UI中显示在线人数的视图界面单元；

本发明一种用于直播中更新在线人数的系统的优点在于：数据接 收模块接收到弹幕服务器发送的直播间当前在线人数，同时接收的直播间当前在线人数被抛送给视图控制器，视图控制器向子界面抛出更新直播客户端UI的通知，子界面即可进行在线人数显示的更新，便于主播或观众掌握直播间的当前人气，整个直播间当前在线人数更新过程逻辑分明，且实施方便。
附图说明
图1为本发明一种用于直播中更新在线人数的方法的流程图。
具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明实施例提供一种用于直播中更新在线人数的方法，用于对iOS系统中直播客户端内直播间在线人数的更新，本发明实施例中，直播客户端位于操作系统为iOS系统的智能移动设备中，智能移动设备为手机或平板电脑。具体包括：
S1：直播客户端接收弹幕服务器发送的直播间当前在线人数，弹幕服务器以消息的形式向直播客户端发送直播间当前在线人数，且弹幕服务器发送给直播客户端消息有多种类型，直播间当前在线人数属于房间人数变化类消息。直播客户端使用函数receiveAssistMessageWithType接受弹幕服务器发送过来的消息，函数receiveAssistMessageWithType中的参数hostType用以表示服务器类型，此处代表弹幕服务器。
弹幕服务器发送给直播客户端消息的类型，如：弹幕文字类、人数变化类，人数变化类又分为全部直播人数变化类、房间人数变化类等等，因此当直播客户端收到弹幕服务器发送的消息后，需使用函数isEqualToString判断收到的消息的类型是否为人数变化类，若是人数 变化类，则对消息进行相关的逻辑处理，并使用函数receiveAssistMessageWithType进一步判断消息是否为receiveAssistMessageWithType类型，receiveAssistMessageWithType类型即表示为房间人数变化类，因为直播间观看人数的变化属于房间内地消息，对此，直播客户端只需对房间人数变化类消息进行处理。
S2：直播客户端以代理方式将直播间当前在线人数发送至iOS系统的视图控制器，发送至iOS系统的视图控制器中的直播间当前在线人数，被转化为long long型的数据类型，long long型是Objective-C语言的一种数据类型，类似double类型。房间人数变化类消息中直播间当前在线人数的获取通过函数[decoder getItem:@"uc"]，同时可以将获取的直播间当前在线人数记为usercount。
直播间当前在线人数通过代理函数抛至iOS系统的视图控制器，代理函数为socketKeepLive。通过代理方式将直播间当前在线人数抛出方式，根据iOS系统的代理特性，只需代理遵从视图服务器的代理协议，同时实现-(void)socketKeepLive:(NSString*)usercount这个函数，视图服务器便能够接受到代理抛出的直播间当前在线人数，整个消息的通知和接收简单，同时仅需视图服务器对直播间当前在线人数消息进行处理，无需其它控制器对消息的前期处理，简化操作。
S3：根据获得的直播间当前在线人数，视图控制器以代理方式向子界面抛出更新直播客户端UI(User Interface，用户界面)的通知，直播客户端UI为智能移动设备中直播客户端软件的UI，子界面为直播客户端UI中显示在线人数的视图界面单元，通知的抛出操作在直播客户端的主线程中进行。更新直播客户端UI的通知中含有一执行代码，执行代码用于根据获取的直播间当前在线人数更新子界面中的 在线人数显示。根据iOS系统语言的开发特性，更新UI必须在应用的主线程中进行，因此，更新直播客户端UI的通知的抛出操作和执行代码的执行均需在直播客户端的主线程中进行。视图控制器用于控制直播客户端UI的显示，直播客户端UI由多个视图界面单元组成，每个视图界面单元所显示内容类别不同，每个视图界面单元均对应一子界面，子界面即view，由视图控制器控制，视图控制器控制即为iOS系统中的ViewController。本发明实施例中子界面为直播客户端UI中显示在线人数的视图界面单元。
执行代码具体为：
Figure PCTCN2018081278-appb-000001
更新直播客户端UI的通知为一声明函数，执行代码位于所述声明函数中，且执行代码的执行在直播客户端的主线程中进行。申明函数为executeInMainQueue，该函数中有一参数block，block即为执行代码。为保证直播间当前在线人数更新的正常进行，当更新直播客户端UI的通知抛出后：
S301：判断更新直播客户端UI的通知中是否含有执行代码，若有，转到S402，若没有，则结束，即申明函数的执行终止。通过判断执行代码是否存在，是为了避免传入一执行代码为空的情况，从而导致直播客户端程序崩溃。
S302：判断执行代码的执行是否在主线程中进行，若是，转到S4，若不是，则将执行代码的执行操作调回主线程中，然后转到S4。执行代码的执行是否在主线程中通过函数[NSThreadisMainThread]进行判断，若不在主线程，则使用函数dispatch_async(dispatch_get_main_queue(),block)将执行代码的执行操作调回主线程中。
当完成S401和S402的判断确认后，即可进行更新直播客户端UI的通知的抛出过程操作：在执行代码中，使用函数respondsToSelector判断setPersonNum:number:这个函数的实现是否存在，若存在，则使用函数[self.danmuDelegatenumber:count]；将更新直播客户端UI以代理方式向子界面抛出。
S4：子界面获取更新直播客户端UI的通知，进行子界面中在线人数显示的更新。
直播客户端与弹幕服务器间基于socket(编程接口)进行通讯，socket是一个通信链的句柄，用来实现不同虚拟机、不同计算机或不同设备之间的通信，使用socket将房间人数变化类消息从弹幕服务器传输到直播客户端，socket通信的数据量大且迅速，且占用的服务器资源小，能够有效保证房间人数变化类消息传输的时效性。同时，弹幕服务器按预设时间间隔向直播客户端发送房间人数变化类消息，从而在线人数的更新频率可以控制，使用灵活。
本发明实施例中用于直播中更新在线人数的方法，通过弹幕服务器将房间人数变化类消息发送给直播客户端，便于直播客户端进行直播间当前在线人数的更新，弹幕服务器进行消息推送主动控制的方式，便于后台人员对消息推送的频率进行灵活控制；同时，使用两级代理，从接收的房间人数变化类消息中获取直播间当前在线人数以代 理的方式抛给视图控制器，视图控制器以代理方式向子界面抛出更新直播客户端UI的通知，有效的对事件的分发做了处理，各自完成各自消息的抛出发送，事件逻辑处理清晰；子界面接收到更新直播客户端UI的通知后，即可完成直播间的在线人数的更新，有效反应直播间的当前人气。
本发明实施例还公开了一种基于上述用于直播中更新在线人数的方法的用于直播中更新在线人数的系统，包括：数据接收模块、数据传输模块和数据更新模块。
数据接收模块用于接收弹幕服务器向直播客户端发送的直播间当前在线人数；数据传输模块用于将数据接收模块接收的直播间当前在线人数发送至iOS系统的视图控制器中，以及控制视图控制器根据获得的直播间当前在线人数向子界面抛出更新直播客户端UI的通知，且通知的抛出操作在直播客户端的主线程中进行，子界面为直播客户端UI中显示在线人数的视图界面单元；数据更新模块用于根据更新直播客户端UI的通知，进行子界面中在线人数显示的更新。
更新直播客户端UI的通知中含有一执行代码，执行代码用于根据获取的直播间当前在线人数更新子界面中的在线人数显示。弹幕服务器按预设时间间隔向直播客户端发送房间人数变化类消息。
本发明实施例中用于直播中更新在线人数的系统：数据接收模块接收到弹幕服务器发送的直播间当前在线人数，同时接收的直播间当前在线人数被抛送给视图控制器，视图控制器向子界面抛出更新直播客户端UI的通知，子界面即可进行在线人数显示的更新，便于主播或观众掌握直播间的当前人气，整个直播间当前在线人数更新过程逻辑分明，且实施方便。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员 来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
