大部分代码来源于一个Demo中的一个功能点， Demo已经给不知道地址了， 囧。
主要代码如下： 播放器组件类

视图只设置了 6+ 的适配， 其他的没做处理。
调用
self.view.backgroundColor = [UIColor blackColor];
NSURL *url = [NSURL URLWithString:@"http://baobab.wdjcdn.com/14562919706254.mp4"];
// NSURL *url = [[NSBundle mainBundle] URLForResource:@"minion_01" withExtension:@"mp4"];
[_playView setUrl:url];效果：
实现了， 暂停， 拖放，声音，亮度， 锁屏。 这一些基本简单操作。
