iOS之视频

1.AVPlayer

工具栏需要自定义订制。

#import <AVFoundation/AVFoundation.h>

@property (nonatomic, strong)AVPlayer *player;

-(AVPlayer *)player
{
    if (_player == nil) {
        //1.获取URL（远程/本地）
     NSURL *url = [[NSBundle mainBundle] URLForResource:@"周杰伦.mp4" withExtension:nil];
   //NSURL *url = [NSURL URLWithString:@"http://v1.mukewang.com/a45016f4-08d6-4277-abe6-bcfd5244c201/L.mp4"];
        
        //2.创建AVPlayerItem
       AVPlayerItem *item = [AVPlayerItem playerItemWithURL:url];

        //3.创建AVPlayer
        _player = [AVPlayer playerWithPlayerItem:item];

        //4.添加AVPlayerLayer
        AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:_player];
        layer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.width * 9/16);
        layer.backgroundColor = [UIColor redColor].CGColor;
        [self.view.layer addSublayer:layer];

    }
    return _player;
}
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.player play];
}

2.MPMoviePlayerController

自带工具栏，有非常多通知方法。

#import <MediaPlayer/MediaPlayer.h>
@property (nonatomic ,strong)MPMoviePlayerController *playController;

-(MPMoviePlayerController *)playController
{
    if (_playController == nil) {
        //1.获取视频的URL
        NSURL *url = [NSURL URLWithString:@"http://v1.mukewang.com/3e35cbb0-c8e5-4827-9614-b5a355259010/L.mp4"];
        
        //2.创建控制器
        _playController = [[MPMoviePlayerController alloc] initWithContentURL:url];
        
        //3.设置控制器的View的位置
        _playController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.width * 9/16);
        
        //4.将view添加到控制器上
        [self.view addSubview:_playController.view];
        
        //5.设置属性，隐藏工具栏
       // _playController.controlStyle = MPMovieControlStyleNone;
    }
    return _playController;
}


-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.playController play];
}

3.MPMoviePlayerViewController

全屏播放

#import <MediaPlayer/MediaPlayer.h>

@property (nonatomic ,strong)MPMoviePlayerViewController *playViewContrller;

-(MPMoviePlayerViewController *)playViewContrller
{
    if (_playViewContrller == nil) {
        NSURL *url = [NSURL URLWithString:@"http://v1.mukewang.com/3e35cbb0-c8e5-4827-9614-b5a355259010/L.mp4"];
        
        _playViewContrller = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
    
    }
    return _playViewContrller;
}

-(void)play
{
    [self presentMoviePlayerViewControllerAnimated:self.playViewContrller];
}

4.区别

1.AVAudioPlayer(本地音乐)

2.AVPlayer（远程音乐/播放视频）-> 添加到layer

3.MPMoviePlayerController -> 给view设置frame，将这个view添加到某个view上

4.MPMoviePlayerViewController(modal出来,自动播放，一定会全屏播放）
