// 设置媒体源数据

_playerViewController.player = [AVPlayer playerWithURL:url];

// 设置拉伸模式

_playerViewController.videoGravity = AVLayerVideoGravityResizeAspect;

// 设置是否显示媒体播放组件

// 设置代理

//    _playerViewController.delegate = self;

// 播放视频

// 设置媒体播放器视图大小

_playerViewController.view.bounds = CGRectMake(0, 0, 475, 250);

_playerViewController.view.center = CGPointMake(CGRectGetMidX(self.view.bounds),44+  CGRectGetMidY(_playerViewController.view.bounds) );

// 4、推送播放
