iOS上的播放受限于来自YouTube API的VEVO视频 [英] Playback restricted on iOS for VEVO videos from YouTube API

问题描述

我已根据建议使用UIWebView将视频（从YouTube API v3中提取）嵌入到我的iPhone应用中。问题是某些视频（例如来自VEVO的视频）在尝试在设备上播放时会产生以下错误。

I have embedded videos (pulled from YouTube API v3) into my iPhone app using a UIWebView as suggested. The problem is that some videos, such as those from VEVO, produce the following error when attempting to play them on the device.

此视频包含来自VEVO的内容。限制在某些网站上播放。

This video contains content from VEVO. It is restricted from playback on certain sites.

这不应该发生，因为像Flipboard和Rockpack这样的应用似乎也是如此使用UIWebView，能够播放来自VEVO和其他来源的视频。

This should not occur, since apps like Flipboard and Rockpack also seem to be using a UIWebView, and are able to play videos from VEVO and other sources.

我可能做错了什么？

PS：我知道有其他帖子以某种方式触及这个问题，但是他们无法解决这个具体问题。

推荐答案

使用YouTube的 YTPlayerView for iOS和将 origin 属性设置为有效的URL可以正常播放许多VEVO视频。

Using YouTube's YTPlayerView for iOS and setting the origin property to a valid URL allows many VEVO videos to be played properly.

在视图控制器中：

@property (weak, nonatomic) IBOutlet YTPlayerView *playerView;

// ..

NSDictionary *playerVars = @{
                             @"playsinline" : @1,
                             @"showinfo" : @0,
                             @"rel" : @0,
                             @"controls" : @1,
                             @"origin" : @"https://www.example.com", // this is critical
                             @"modestbranding" : @1
                             };

[self.playerView loadWithVideoId:@"Ri7-vnrJD3k" playerVars:playerVars];
