场景
公司新项目是一个直播类型的项目,要求实现类似熊猫or斗鱼那种退出直播详情界面衔接一个悬浮(可随意拖动)的播放器继续播放.
考虑到无缝衔接的需求和重新加载延迟缓冲的问题,大体定下一个思路是用一个单例对象来实现这个功能,单例对象包含一个播放器对象和一些需要用的参数等.
效果
-w415
实现
播放器使用了网易直播提供的NELivePlayer,集成该播放器可以参考网易官网的集成文档:http://vcloud.163.com/docs/live/player.html 播放器底层使用的是bilibili开源的ijkplaer
注:只能真机调试,模拟器播放器会创建失败.
流程:
1.创建PlayerShowView对象传入直播url
2.PlayerShowView内部获取PlayObj单利对象,传入直播url,获得播放器视图,添加到自身
3.PlayObj获取到直播url,判断是否已经有创建的播放器对象 || 是否是正在播放的直播等做不同操作
4.退出播放详情页-调用delloc时发送一个通知,在根视图控制器接受消息创建悬浮播放器
