AVPlayerViewController简介

iOS8之后系统自带使用AVPlayerViewController来播放视频

1.导入头文件

#import <AVKit/AVKit.h>
#import <AVFoundation/AVFoundation.h>

2.声明属性

@property (nonatomic, strong) AVPlayer *player;
@property (nonatomic, strong) AVPlayerViewController *playerViewController;

3.实现播放代码

_player = [AVPlayer playerWithURL:[NSURL URLWithString:@"*.mp4"]]; 
_playerViewController = [[AVPlayerViewController alloc] init]; _playerViewController.player = _player;
//设置AVPlayer的填充模式
_playerViewController.videoGravity = AVLayerVideoGravityResizeAspect; 
// _playerViewController.allowsPictureInPicturePlayback = true; //画中画，iPad可用
//_playerViewController.showsPlaybackControls = true;
_playerController.view.translatesAutoresizingMaskIntoConstraints = true; //这句可以禁用自动约束，消除报错

备注：AVPlayerViewController本身支持横屏和竖屏播放
