AVPlayer ---- 视频播放器常规功能 ios

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：
