[操作系统]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)
