利用AVPlayerViewController实现点击cell中的button播放视频

#import <AVFoundation/AVFoundation.h>

AHUPlayerViewController.h中声明的topic是本人项目中用于取视频url等信息的数据模型

@interface AHUPlayerViewController ()

@property (nonatomic, strong) AVPlayerViewController  *playerView;

@end

@implementation AHUPlayerViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    //视频播放的url
    NSURL *playerURL = [NSURL URLWithString:self.topic.videouri];
    
    //初始化
    self.playerView = [[AVPlayerViewController alloc]init];
    
    //AVPlayerItem 视频的一些信息  创建AVPlayer使用的
    AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:playerURL];
    
    //通过AVPlayerItem创建AVPlayer
    self.player = [[AVPlayer alloc] initWithPlayerItem:item];
    
    //AVPlayerViewController内部的约束
    self.playerView.view.translatesAutoresizingMaskIntoConstraints = NO;
}

@end

在videoView中监听，点击了封面图片或播放按钮都会调用seeVideo方法，弹出视频播放界面

- (void)awakeFromNib
{
    [super awakeFromNib];
    //从xib中加载进来的空间的autoresizingMask默认是UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight
    self.autoresizingMask = UIViewAutoresizingNone;
    
    self.imageView.userInteractionEnabled = YES;
    [self.imageView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(seeVideo)]];
    [self.playButton addTarget:self action:@selector(seeVideo) forControlEvents:UIControlEventTouchUpInside];
}

- (void)seeVideo
{
    AHUPlayerViewController *videoView = [[AHUPlayerViewController alloc] init];
    videoView.topic = self.topic;
    [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:videoView animated:YES completion:nil];
}
