如何在iOS中下载YouTube视频 [英] How do I download a youtube video in iOS

问题描述

我知道如何在iOS网页视图中推出YouTube视频，但如何下载该视频以保存在iPad应用上？可能吗？我需要使用一些NSURLConnection对象的调用，然后将接收的数据保存到正确的文件格式？

我不确定的一个特定的点是什么url请求文件将被。当您在YouTube上观看视频时，可以下载的视频被触发一个按钮，所以对我来说这不是很明显的URL。

解决方案

您需要下载iOS兼容版本的视频，可能使用与 Safari FlashToHTML5插件。

Youtube提供视频下载链接：

..确保你不违反他们的TOS。

$一般来说，下载大文件时，您可以考虑实现可恢复文件下载，espe因为移动设备上的连接是短暂的。

此外，请确保您在下载（或恢复下载）时使用WiFi网络，使用可达性。请注意，超过蜂窝网络的带宽过多是应用程序拒绝的原因。

I know how to launch a youtube video within an iOS web view, but how can I download that video to save on my iPad app? Is it possible? Do I need to use some call with a NSURLConnection object and then save the received data into the proper file format?

One specific point I am unsure about is what the url to request the file would be. When viewing a video on youtube, the downloadable videos are triggered with a button, so it's not evident to me what the url would be.

解决方案

You would need to download an iOS-compatible version of the video, possibly using the same technique employed by the Safari FlashToHTML5 plugin.

Youtube DOES offer video download links:

.. make sure you do not violate their TOS.

In general, when downloading large files, you might consider implementing resumable file downloads, especially because connectivity on a mobile device is transient.

On top of that, make sure that you're on a wifi network when downloading (or resuming a download), using Reachability. Note that excessive bandwidth usage over cellular networks is a reason for app rejection.
