视图只设置了 6+ 的适配， 其他的没做处理。
调用
self.view.backgroundColor = [UIColor blackColor];
[objc]view plaincopy
NSURL*url = [NSURLURLWithString:@"http://baobab.wdjcdn.com/14562919706254.mp4"];
NSURL*url = [[NSBundlemainBundle]URLForResource:@"minion_01"withExtension:@"mp4"];
[_playViewsetUrl: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。
