AVPlayerViewController视频播放器

前言

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

AVPlayerViewController

AVPlayerViewController和导航控制器差不多，需要将它添加在一个视图控制器上，将它的视图添加视图上

1.导入头文件

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

2.声明成员变量

   AVPlayerViewController      *_playerController;
    AVPlayer                    *_player;
    AVAudioSession              *_session;
    NSString                    *_urlString;

3.使用播放器

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    _session = [AVAudioSession sharedInstance];
    [_session setCategory:AVAudioSessionCategoryPlayback error:nil];
    
    _player = [AVPlayer playerWithURL:[NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"]];
    _playerController = [[AVPlayerViewController alloc] init];
    _playerController.player = _player;
    _playerController.videoGravity = AVLayerVideoGravityResizeAspect;
    _playerController.allowsPictureInPicturePlayback = true;    //画中画，iPad可用
    _playerController.showsPlaybackControls = true;
    
    [self addChildViewController:_playerController];
    _playerController.view.translatesAutoresizingMaskIntoConstraints = true;    //AVPlayerViewController 内部可能是用约束写的，这句可以禁用自动约束，消除报错
    //self.view.bounds
    _playerController.view.frame = CGRectMake(0, 0, 320, 300);
    [self.view addSubview:_playerController.view];
    [_playerController.player play];    //自动播放
}

4.如果要使用iOS9的画中画（仅限平板）
