Question

我有一个UITableView，用于渲染包含gif的推文。这些都是从Twitter作为MP4返回的，所以我正在使用AVPlayer。我使用HanekeSwift缓存项目，然后在表视图中播放它。我遇到的问题是加载tableview时屏幕上的任何推文都不会自动播放，我必须在屏幕上滚动这些推文然后重新打开。

我通过以下功能配置AVPlayer

private func configureAVPlayer(url: URL) {
    cache.fetch(URL: url).onSuccess { [weak self] stream in
        guard let path = URL(string: DiskCache.basePath())?.appendingPathComponent("shared-data/original") else { return }

        let cached = DiskCache(path: path.absoluteString).path(forKey: url.absoluteString)
        let file = URL(fileURLWithPath: cached)

        if !FileManager.default.fileExists(atPath: cached) {
            try! stream.write(to: file, options: .atomicWrite)
        }

        self?.player = AVPlayer(url: file)
        self?.player?.automaticallyWaitsToMinimizeStalling = false
        self?.playerLayer = self?.avPlayerView.layer as? AVPlayerLayer
        guard let player = self?.player else { return }
        self?.playerLayer?.player = player
        self?.player?.play()
    }
}

遵循与here类似的内容

但是，对我而言，该单元格基本上已暂停，直到我滚动为止。

直到回收电池，AVPlayer才会启动
