背景视频Objective-c

Question

我想在我的视图中播放循环背景视频。我写了这个代码：

-(AVPlayerLayer*)playerLayer{ 

    if(!_playerLayer){ 

    // find movie file 
    NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"fond_login" ofType:@"mp4"]; 
    NSURL *movieURL = [NSURL fileURLWithPath:moviePath]; 
    _playerLayer = [AVPlayerLayer playerLayerWithPlayer:[[AVPlayer alloc]initWithURL:movieURL]]; 
    _playerLayer.frame = CGRectMake(0,0,self.view.frame.size.width, self.view.frame.size.height); 
    [_playerLayer.player play]; 
    return _playerLayer; 
} 
return nil; } 

-(void)replayMovie:(NSNotification *)notification { 
NSLog(@"Finis"); 
[self.playerLayer.player play];} 

在我viewDidLoad中，我有：

[self.view.layer addSublayer:self.playerLayer]; 
[[NSNotificationCenter defaultCenter] addObserver: self 
             selector: @selector(replayMovie:) 
              name: AVPlayerItemDidPlayToEndTimeNotification 
              object:nil]; 

我的问题是，视频不循环播放。我一次看到视频并完成。我不知道为什么..

感谢的

编辑：

我看到另一个教程。

@import MediaPlayer; 

@property (nonatomic, strong) MPMoviePlayerController *moviePlayer; 

我在viewDidLoad中代码：

NSURL *videoURL = [[NSBundle mainBundle] URLForResource:@"my_video" withExtension:@"format"]; 

self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL]; 
self.moviePlayer.controlStyle = MPMovieControlStyleNone; 
self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill; 
self.moviePlayer.view.frame = self.view.frame;[self.view insertSubview:self.moviePlayer.view atIndex:0]; 
[self.moviePlayer play]; 

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loopVideo) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer]; 

和：

- (void)loopVideo { 
[self.moviePlayer play]; } 

它的工作完美。

在你replayMovie:方法，你需要寻求回到开头：

- (void)replayMovie:(NSNotification *)notification { 
    [(AVPlayerItem *)notification.object seekToTime:kCMTimeZero]; 
} 

您还打算要设置的AVPlayer的actionAtItemEnd因此不会暂停：

_playerLayer.player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
