Youtube API 身份验证 - Iphone

Question

我正在尝试使用youtube api的示例代码上传视频。当我按下上传按钮时，进度条完成其过程，但是一旦到达点的末尾，我就会出错。错误描述如下：

YouTubeTest[2149：f803] 错误 - 错误 Domain=com.google.GDataServiceDomain Code=400 "操作无法 完成。（com.google.GDataServiceDomain error 400.）" UserInfo=0x69d5bd0 {}

这是按下上传按钮的代码

- (IBAction)uploadPressed:(id)sender {
    [self.view resignFirstResponder];
    NSString *devKey = [mDeveloperKeyField text];
    GDataServiceGoogleYouTube *service = [self youTubeService];
    [service setYouTubeDeveloperKey:devKey];
    NSString *username = [mUsernameField text];
    NSString *clientID = [mClientIDField text];
    NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username
                                                             clientID:clientID];
    // load the file data
    NSString *path = [[NSBundle mainBundle] pathForResource:@"YouTubeTest" ofType:@"m4v"]; 
    NSData *data = [NSData dataWithContentsOfFile:path];
    NSString *filename = [path lastPathComponent];
    // gather all the metadata needed for the mediaGroup
    NSString *titleStr = [mTitleField text];
    GDataMediaTitle *title = [GDataMediaTitle textConstructWithString:titleStr];
    NSString *categoryStr = [mCategoryField text];
    GDataMediaCategory *category = [GDataMediaCategory mediaCategoryWithString:categoryStr];
    [category setScheme:kGDataSchemeYouTubeCategory];
    NSString *descStr = [mDescriptionField text];
    GDataMediaDescription *desc = [GDataMediaDescription textConstructWithString:descStr];
    NSString *keywordsStr = [mKeywordsField text];
    GDataMediaKeywords *keywords = [GDataMediaKeywords keywordsWithString:keywordsStr];
    BOOL isPrivate = mIsPrivate;
    GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup];
    [mediaGroup setMediaTitle:title];
    [mediaGroup setMediaDescription:desc];
    [mediaGroup addMediaCategory:category];
    [mediaGroup setMediaKeywords:keywords];
    [mediaGroup setIsPrivate:isPrivate];
    NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:path
                                               defaultMIMEType:@"video/mp4"];
    // create the upload entry with the mediaGroup and the file data
    GDataEntryYouTubeUpload *entry;
    entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup
                                                          data:data
                                                      MIMEType:mimeType
                                                          slug:filename];
    SEL progressSel = @selector(ticket:hasDeliveredByteCount:ofTotalByteCount:);
    [service setServiceUploadProgressSelector:progressSel];
    GDataServiceTicket *ticket;
    ticket = [service fetchEntryByInsertingEntry:entry
                                      forFeedURL:url
                                        delegate:self
                               didFinishSelector:@selector(uploadTicket:finishedWithEntry:error:)];
    [self setUploadTicket:ticket];
}

我已经从 API 仪表板正确设置了开发人员密钥和客户端密钥。

我正在模拟器上运行它。是我们不能从模拟器上传视频吗？

请指导我哪里出错了？

错误已解决...使用谷歌帐户将视频上传到YouTube时，GData的某些功能Objective-C需要Gmail帐户作为参数，有些需要YouTube关联的帐户作为参数。

当您调用"- （void）setUserCredentialsWithUsername：（NSString *）用户名密码：（NSString *）password;' 在 GDataServiceBase 中，用户名应该是Gmail帐户，例如"[e-mail]"，密码应该是Gmail帐户。

但是当你调用'+ （NSURL *）youTubeUploadURLForUserID：（NSString *）userID clientID：（NSString *）clientID;' in GDataServiceGoogleYouTube，用户 ID 参数应为 YouTube 关联的帐户，并且密码 Gmail 帐户的密码。

我正在使用 [e-mail] 登录，现在我只是使用email_id登录。多么愚蠢的错误..但是我花了整整2天的时间来解决。.咄..！！
