ios - YTPlayer将重定向到OAuth2 URL并显示“请稍候”

Question

我正在尝试使用YTPlayer在iOS App中播放直播。

我使用简单的代码，仅将“videoId”更改为“w-T2LJ_qLiw”，这是YouTube上的实时视频。

但是，当视频加载后，应用程序将打开Safari并重定向到URL，如下所示:

https://accounts.google.com/o/oauth2/postmessageRelay?parent=https%3A%2F%2Fwww.youtube.com#rpctoken=840721360&forcesecure=1

和

https://content.googleapis.com/static/proxy.html?jsh=m%3B%2F_%2Fscs%2Fabc-static%2F_%2Fjs%2Fk%3Dgapi.gapi.en.dPxK-DAj_pE.O%2Fm%3D__features__%2Fam%3DAAQ%2Frt%3Dj%2Fd%3D1%2Frs%3DAItRSTN0fuoBkyFaoHWfzWWLct0BxZgQSQ#parent=https%3A%2F%2Fwww.youtube.com&rpctoken=2021820196

然后将加载并播放视频，但会被黑色方框显示“请稍候”。

如果视频不是“实时”的，则视频播放良好。

我昨天之前尝试过，效果很好。 YTPlayer发生了什么？
我需要通过代码控制视频的操作，例如播放，暂停，重新加载。
有什么我可以解决的吗？

尽管周义棠的解决方案可能有效，但它违反了YouTube的服务条款。我修改了handleHttpNavigationToUrl:方法，以在将用户带出UIWebView并进入Safari之前检查这两个其他URL。

这是我的工作解决方案:

// YTPlayerView.m

// ...

NSString static *const kYTPlayerOAuthRegexPattern = @"^http(s)://accounts.google.com/o/oauth2/(.*)$";
NSString static *const kYTPlayerStaticProxyRegexPattern = @"^https://content.googleapis.com/static/proxy.html(.*)$";

// ...

- (BOOL)handleHttpNavigationToUrl:(NSURL *) url {
  // Usually this means the user has clicked on the YouTube logo or an error message in the
  // player. Most URLs should open in the browser. The only http(s) URL that should open in this
  // UIWebView is the URL for the embed, which is of the format:
  //     http(s)://www.youtube.com/embed/[VIDEO ID]?[PARAMETERS]
  NSError *error = NULL;
  NSRegularExpression *ytRegex =
      [NSRegularExpression regularExpressionWithPattern:kYTPlayerEmbedUrlRegexPattern
                                                options:NSRegularExpressionCaseInsensitive
                                                  error:&error];
  NSTextCheckingResult *ytMatch =
      [ytRegex firstMatchInString:url.absoluteString
                        options:0
                          range:NSMakeRange(0, [url.absoluteString length])];

  NSRegularExpression *adRegex =
      [NSRegularExpression regularExpressionWithPattern:kYTPlayerAdUrlRegexPattern
                                                options:NSRegularExpressionCaseInsensitive
                                                  error:&error];
  NSTextCheckingResult *adMatch =
      [adRegex firstMatchInString:url.absoluteString
                        options:0
                          range:NSMakeRange(0, [url.absoluteString length])];

  NSRegularExpression *oauthRegex =
      [NSRegularExpression regularExpressionWithPattern:kYTPlayerOAuthRegexPattern
                                              options:NSRegularExpressionCaseInsensitive
                                                error:&error];
  NSTextCheckingResult *oauthMatch =
    [oauthRegex firstMatchInString:url.absoluteString
                           options:0
                             range:NSMakeRange(0, [url.absoluteString length])];

  NSRegularExpression *staticProxyRegex =
    [NSRegularExpression regularExpressionWithPattern:kYTPlayerStaticProxyRegexPattern
                                              options:NSRegularExpressionCaseInsensitive
                                                error:&error];
  NSTextCheckingResult *staticProxyMatch =
    [[staticProxyRegex firstMatchInString:url.absoluteString
                                  options:0
                                    range:NSMakeRange(0, [url.absoluteString length])];

  if (ytMatch || adMatch || oauthMatch || staticProxyMatch) {
    return YES;
  } else {
    [[UIApplication sharedApplication] openURL:url];
    return NO;
  }
}

我还已在项目的GitHub上将此更改建议为PR #111。

编辑6/10/15:到今天为止，此修改已合并到代码库中。
