Question

在单元格中有视频时，我只想显示视频（在avPlayerViewController中），如果没有视频，则它会执行到详细视图的搜索

我已经尝试过了：

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {


    let post = postArray[indexPath.item]
    let controller = PostDetailViewController.fromStoryboard(post: post)
    self.navigationController?.pushViewController(controller, animated: true)


    guard let videoURL = URL(string: post.videoLink)  else {
        return
            }

    let avPlayer = AVPlayer(url: videoURL)
    let avController = AVPlayerViewController()
    avController.player = avPlayer

    present(avController, animated: true) {
        avPlayer.play()
    }

}

如果有一个视频（来自Firebase），它将播放视频，但也会打开详细视图。因此，我希望该单元仅打开视频或仅打开detailview

对其进行结构化，以便在没有post.videoLink的情况下按PostDetailViewController，否则它将播放视频：

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    guard let videoURL = URL(string: post.videoLink) else {
        //If there is no URL, then this else condition will be called. Otherwise, the code below the guard statement will be called, and the video player will appear.
        let post = postArray[indexPath.item]
        let controller = PostDetailViewController.fromStoryboard(post: post)
        self.navigationController?.pushViewController(controller, animated: true)
        return
    }

    let avPlayer = AVPlayer(url: videoURL)
    let avController = AVPlayerViewController()
    avController.player = avPlayer

    present(avController, animated: true) {
        avPlayer.play()
    }

}

从一个单元格（不同视图和一个avcontroller）隔离到不同的控制器
