直播播放器使用

播放器功能特性

与系统播放器MPMoviePlayerController接口一致，可以无缝快速切换至KSYMediaPlayer；

本地全媒体格式支持, 并对主流的媒体格式(mp4, avi, wmv, flv, mkv, mov, rmvb 等 )进行优化；

支持广泛的流式视频格式, HLS, RTMP, HTTP Rseudo-Streaming 等；

更详细使用 查看 https://github.com/ksvc/KSYMediaPlayer_iOS

使用cocopods导入SDK

pod ‘Socket.IO-Client-Swift’

由于苹果上架要求 不得包含UIWebView 而项目中libksybase.a 包含UIWebView

解决方法：从github下载：https://github.com/ksvc/KSYMediaPlayer_iOS;
找到这个.a文件替换工程里的的，每次pod update都要重新替换一次。有点繁琐
其他方法 参考：https://ask.csdn.net/questions/1303736

#pragma mark - 前后台 支持前后台播放  需要info.plist 配置
/*
 如何实现后台播放
 需要APP有后台执行权限，在工程Info.plist中添加后台运行模式，设置为audio。具体是添加UIBackgroundModes项，值为audio。
 当用户点击home按钮后，播放器进入后台继续读取数据并播放音频。
 当APP回到前台后，音频继续播放。图像渲染内容保持和音频同步。
 如果在开启后台运行模式后，需要实现切换到后台暂停音频，需要监听相关事件并主动调用pause操作。
