无法通过目标C在iOS13.x上获得AVPlayerLayer

Question

我正在用objective制作一个iOS应用程序。

请告诉我如何在iOS13.x环境中修复AVPlayerView。

M写

AVPlayerLayer* layer = (AVPlayerLayer*)self.videoView.layer;

VideoView包含AVPlayerView

AVPlayerView.m写

#import "AVPlayerView.h"
#import <AVFoundation/AVFoundation.h>

@implementation AVPlayerView

+(Class)layerClass{
    return AVPlayerLayer.class;
}

@end

由于某些原因，不需要调用layerClass方法。

另外，(AVPlayerLayer *) self.videoView.layer返回的类

AVPresentationVontainerViewLayer。

我想要一个AVPlayerView课程。

我该怎么修呢？

Answer 1

试试这个：

    NSURL *url = [NSURL fileURLWithPath:path];
    AVPlayer *player = [AVPlayer playerWithURL:url];
    AVPlayerViewController *AVPlayerVc = [[AVPlayerViewController alloc] init];
    AVPlayerVc.player = player;
    if (AVPlayerVc) {
        [self presentViewController:AVPlayerVc animated:YES completion:^{
            [player play];
        }];
    }

迅捷版：

 let player = AVPlayer(url: YOUR_URL)
 let playerController = AVPlayerViewController()
 playerController.player = player
 present(playerController, animated: true) {
         player.play()
 }
