当没有互联网连接时，谷歌目标c api:completionHandler从不调用

Question

iOS初学者，我正在尝试使用谷歌目标c api在youtube上上传视频。在大多数情况下，它只是起作用。视频可以上传，如果出现错误，我的回调会收到错误。

但是，如果我关闭设备上的互联网连接，则永远不会调用回调。（即使它被称为其他类型的错误，如不正确的标题或不正确的标签）

我个人的猜测是，虽然我为GTLServiceYouTube设置了回调，但我没有明确为GTMOAuth2Authentication设置回调，因此没有调用。但我不知道该如何设置，在任何地方都找不到。

请注意，在我的情况下，我确实需要我的用户能够上传视频，而无需输入他们的凭据，因此需要手动初始化GTMOAuth2Authentication。

这是我的代码，如果我做错了什么，请告诉我如何修复。

    NSString *clientID = @"185815387242-hqo2d4e06j4hk4f02t5gvn7jcifakdvr.apps.googleusercontent.com";
    NSString *clientSecret = @"2LKi7orHyphJXXXXXXXXXXXX";
    NSURL *tokenURL = [NSURL URLWithString:@"https://accounts.google.com/o/oauth2/token"];
    NSString *redirectURI = @"urn:ietf:wg:oauth:2.0:oob";

    GTMOAuth2Authentication *auth;
    auth = [GTMOAuth2Authentication authenticationWithServiceProvider:kGTMOAuth2ServiceProviderGoogle
                                      tokenURL:tokenURL
                                      redirectURI:redirectURI
                                      clientID:clientID
                                      clientSecret:clientSecret];

    [auth setKeysForResponseString:@"email=annonce-video-i-6620%40pages.plusgoogle.com&isVerified=1&refresh_token=1%2FFFo5rlNs51u9g2TpCIE2oji_ACvDPc0XXXXXXXXXXXX&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube%20https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email&serviceProvider=Google&userID=107586507912247324352"];

我已经追踪到GTMHTTP蚀刻机969 的电话缺失

  @synchronized(self) {
    target = [[delegate_ retain] autorelease];
    sel = finishedSel_;
#if NS_BLOCKS_AVAILABLE
    block = [[completionBlock_ retain] autorelease];
#endif
  }

同步块被调用两次，一次调用GTMOAuth2Authentication回调，第二次调用。。。好无
