AVPlayerViewController視頻播放器，avplayercontroller
前言

iOS8之後系統內建使用AVPlayerViewController播放視頻

AVPlayerViewController

AVPlayerViewController和導航控制器差不多，需要將它添加在一個視圖控制器上，將它的視圖添加視圖上

1.匯入標頭檔

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

2.聲明成員變數

   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;    //畫中畫，iPad可用    _playerController.showsPlaybackControls = true;        [self addChildViewController:_playerController];    _playerController.view.translatesAutoresizingMaskIntoConstraints = true;    //AVPlayerViewController 內部可能是用約束寫的，這句可以禁用自動約束，消除報錯    //self.view.bounds    _playerController.view.frame = CGRectMake(0, 0, 320, 300);    [self.view addSubview:_playerController.view];    [_playerController.player play];    //自動播放}

4.如果要使用iOS9的畫中畫（僅限平板）
