ios - 设置 HLS 缓存策略

Question

一旦 EXT-X-ALLOW-CACHE 被弃用并从协议(protocol)中删除 specification是否有其他方法来设置流的缓存策略？ (我的目标是在客户端启用缓存)

此外，我想在使用 mediastreamvalidator 验证流时消除错误:

您可以在 iOS 10+ 上使用 AVFoundation:

Playing Offline HLS Content

Starting with iOS 10, you can use AVFoundation to download HTTP Live Streaming assets to an iOS device. This new capability allows users to download and store HLS movies on their devices while they have access to a fast, reliable network, and watch them later without a network connection. With the introduction of this capability, HLS becomes even more versatile by minimizing the impact of inconsistent network availability on the user experience
