再生が完了したらAVPlayerを自動的に終了しますか？

Question

私はAVPlayerViewControllerを使ってローカルビデオを再生するアプリを持っています。 しかし、ビデオの再生が終了したら、私はそれを（MPMoviePlayerViewControllerのように）自動的に閉じたいと思います。

この質問を投稿した後、私は以下の回答と、部分的にはAppleの「ガイドとサンプルコード」から部分的に解決することができました。

これは私のために働いたコードです：

#import "ViewController.h" 
@import AVFoundation; 
@import AVKit; 


@interface ViewController() 

@property(nonatomic, readonly) AVPlayerItem *currentItem; 

@end 

@implementation ViewController 

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
} 

- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 

-(void)playerItemDidReachEnd:(NSNotification *) notification { 
    //remove the player 
    [self dismissViewControllerAnimated:YES completion:nil]; 
} 

- (IBAction)playVideo:(id)sender { 

    // grab a local URL to our video 
    NSURL *videoURL = [[NSBundle mainBundle]URLForResource:@"bagare" withExtension:@"mp4"]; 

    // create an AVPlayer 
    AVPlayer *player = [AVPlayer playerWithURL:videoURL]; 

    // create a player view controller 
    AVPlayerViewController *controller = [[AVPlayerViewController alloc]init]; 
    controller.player = player; 
    [player play]; 
    [self presentViewController:controller animated:YES completion:nil]; 

    // show the view controller 
     controller.view.frame = self.view.frame; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
    selector:@selector(playerItemDidReachEnd:) 
    name:AVPlayerItemDidPlayToEndTimeNotification 
    object:_currentItem]; 

    } 

@end 

Answer 1

これは動作するはずです：

[[NSNotificationCenter defaultCenter] addObserver:self 
    selector:@selector(videoDidFinish:) 
    name:AVPlayerItemDidPlayToEndTimeNotification 
    object:[controller.player currentItem]]; 

- (void)videoDidFinish:(id)notification 
{ 
    AVPlayerItem *p = [notification object]; 
    //do something with player if you want 

    [[NSNotificationCenter defaultCenter] removeObserver:self]; 

    //fade out/remove subview 
} 

Answer 2

NSURL *url=[NSURL URLWithString:@"URLLINK"]; 
AVAsset *avAsset = [AVAsset assetWithURL:url]; 
AVPlayerItem *playerItem = [[AVPlayerItem alloc]initWithAsset:avAsset]; 

はAVPlayerItemのDidPlayToEndTime通知を購読します。

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem]; 

新しいプレーヤーここ

AVPlayer *player = [AVPlayer playerWithURL:videoURL] 
    AVPlayerViewController *controller=[[AVPlayerViewController alloc]init]; 
    controller.player=player; 
    [player play]; 
    [self presentViewController:controller animated:YES completion:nil]; 

プレーヤーが解任削除するか、プレーヤーは.hファイルでビュー

-(void)itemDidFinishPlaying:(NSNotification *) notification { 
[self dismissViewControllerAnimated:YES completion:nil]; 
    [[NSNotificationCenter defaultCenter]removeObserver:self name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem]; 
} 

Answer 3

を追加するAVPlayerItemを渡し

.Mファイルで

：

- (IBAction)playVideo:(id)sender { 

    // grab a local URL to our video 
    NSURL *videoURL = [[NSBundle mainBundle]URLForResource:@"bagare" withExtension:@"mp4"]; 

    // create an AVPlayer 
    AVPlayer *player = [AVPlayer playerWithURL:videoURL]; 

    // create a player view controller 
    self.controller = [[AVPlayerViewController alloc]init]; 
    controller.player = player; 
    [player play]; 
    [self presentViewController:controller animated:YES completion:nil]; 

    // show the view controller 
     controller.view.frame = self.view.frame; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
    selector:@selector(playerItemDidReachEnd:) 
    name:AVPlayerItemDidPlayToEndTimeNotification 
    object:_currentItem]; 

    }
