YTPlayer will redirect to OAuth2 URL and shows 'please stand by'

Question

I'm trying to use YTPlayer for played live stream in iOS App.

I use the simple code and only changed 'videoId' to 'w-T2LJ_qLiw' which is live video at YouTube.

But when video loaded, app will open Safari and redirect to URL as following:

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

and

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

Then video will loaded and played but covered will black block shows 'Please stand by.'

If video is not 'live', video plays well.

I tried it before yesterday and it works well. What happened to YTPlayer? I needs to control video's action like, play, pause, reload by code.
Is there any thing I can work around this?

Although 周義棠's solution may work, it breaks YouTube's Terms of Service. I have modified the handleHttpNavigationToUrl: method to check for these two additional URLs before taking the user out of the UIWebView and into Safari.

This is my working solution:

// 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;
  }
}

I have also proposed this change on the project's GitHub as PR #111.
