ios - Youtube 与 iOS 应用程序集成 - 意外错误

Question

我正在关注这个例子 https://code.google.com/p/google-api-objectivec-client/source/browse/#svn/trunk/Examples/YouTubeSample将 YouTube SDK 集成到我的 iOS 应用中。
以下是我做过的一些工作:
- 将 GTL.project 添加到我的项目中，并为 Header Search Path 设置源路径。
- 将 GTLTouchStaticLib 链接到链接二进制文件与我的项目的库。
- 将 GTLYouTube_Sources.m 添加到我的项目中。
- 从 YouTubeSample 复制一些代码，这里是代码片段:

#import "ViewController.h"

#import "GTLYouTube.h"

#import "GTLUtilities.h"
#import "GTMHTTPUploadFetcher.h"
#import "GTMHTTPFetcherLogging.h"
#import "GTMOAuth2ViewControllerTouch.h"
.
.
- (IBAction)Login:(id)sender {

    GTMOAuth2ViewControllerTouch *viewController;
    viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeYouTube
                                                                 clientID:kMyClientID
                                                             clientSecret:kMyClientSecret

    GTLServiceYouTube *service = self.youTubeService;

    GTLQueryYouTube *query = [GTLQueryYouTube queryForChannelsListWithPart:@"contentDetails"];

    query.mine = YES;

    // maxResults specifies the number of results per page.  Since we earlier
    // specified shouldFetchNextPages=YES, all results should be fetched,
    // though specifying a larger maxResults will reduce the number of fetches
    // needed to retrieve all pages.
    query.maxResults = 50;

    // We can specify the fields we want here to reduce the network
    // bandwidth and memory needed for the fetched collection.
    //
    // For example, leave query.fields as nil during development.
    // When ready to test and optimize your app, specify just the fields needed.
    // For example, this sample app might use
    //
    // query.fields = @"kind,etag,items(id,etag,kind,contentDetails)";

    _channelListTicket = [service executeQuery:query
                             completionHandler:^(GTLServiceTicket *ticket,
                                                 GTLYouTubeChannelListResponse *channelList,
                                                 NSError *error) {
                                 // Callback

                                 // The contentDetails of the response has the playlists available for
                                 // "my channel".
                                 if ([[channelList items] count] > 0) {
                                     GTLYouTubeChannel *channel = channelList[0];
                                     _myPlaylists = channel.contentDetails.relatedPlaylists;
                                     NSLog(@"_myPlaylists: %@", _myPlaylists);
                                 }
                                 _channelListFetchError = error;
                                 _channelListTicket = nil;

                                 if (_myPlaylists) {
                                     [self fetchSelectedPlaylist];
                                 }

                                 [self fetchVideoCategories];
                             }];

}

构建并运行后，我使用我的 youtube 帐户登录，当我在页面中单击同意时，应用程序崩溃，错误输出如下:

好像认证成功了，但是fetchMyChannelList失败了:错误发生在为query的mine属性设置值的时候。我已经重新检查了所有步骤，但无法找出问题所在，请帮忙。

我刚刚在使用 Google Calendar api 时遇到了同样的问题。

GTLRuntimeCommon:属性 singleEvents 的意外属性 TB、D

如果您使用的是在 Cocoa Pods 上找到的 Google-API-Client，那么这可能就是原因。我发现在 64 位 iPhone 的查询中设置 bool 值时，cocoapod 有点过时并且会崩溃。来源在这里找到https://code.google.com/p/google-api-objectivec-client/已修复补丁。

如果你对这里的补丁感到好奇 https://code.google.com/p/google-api-objectivec-client/source/detail?r=364
