在iOS应用程序（xcode）中使用本地视频文件

我正在寻找在iOS应用程序中播放视频文件的最佳方式。我的应用程序目前正在开发中，将有大约50个视频（每30秒长）和简短的教程。如果可能的话，我希望它们都是本地的，这样用户就可以在没有互联网连接的情况下观看视频。我在堆栈溢出上找不到类似的问题（可能我找错了部分，如果我错了，请纠正我）

所以我考虑了两种不同的选择：

• 用户从应用商店下载应用程序，包括视频
• 用户下载应用程序时没有视频，首次使用应用程序时必须先下载视频并保存 局部（永久）

如果有更好的选择，我也想知道！

因此，如果有人有这方面的经验，我真的很感谢一些帮助！谢谢

根据用户的观点，人们更喜欢离线模式。并希望在从Appstore下载应用程序时，应用程序大小尽可能小。 所以我的建议是建立一个视频播放器，它既可以在用户在线时播放文件，也可以离线播放可下载或缓存的文件

一种方法是：

使用Web服务器

简单java服务器示例：

检查：

最好是建立一个应用程序，让用户能够下载和存储应用程序内容 从应用商店下载应用程序后。 应用程序应具有删除应用程序下载的视频或清除缓存的选项

down是视频播放器的一个例子，它可以播放离线和在线视频

制作一个定制的电影播放器。。

当您单击TableListView单元格时，使您的播放器视图可见。 制作一个URL下载程序。在中保存文件。

因此，这将允许您保存文件并播放+播放应用程序中已存在的预加载文件。

如果您不需要下载答案，请告诉我。将很高兴更改或删除。@rahul_send89非常感谢您的回答！我会尝试在我的应用程序中实现这一点，看看这是否真的是我想要的，如果是，我会接受你的答案。
