从iPhone应用程序上传视频到YouTube

Question

我想在我的iPhone应用程序上上传视频到YouTube。 我已经尝试过这个http://urinieto.com/2010/10/upload-videos-to-youtube-with-iphone-custom-app/，但最终出现错误。 Domain=com.google.GDataServiceDomain Code=400 "The operation couldn’t be completed. (com.google.GDataServiceDomain error 400.)" UserInfo=0x4d921f0 {}

有人能帮帮我吗？ 谢谢!!!

我的代码

 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];

首先，检查YouTube API是否有任何更新其GData库的内容（上次我使用时发现它们已更改并破坏了我的应用程序）。

下一步，检查一些傻瓜式的问题。已经导入了所有的标头文件，一切都正常吗？

尝试将您的info.plist设置为使用Wi-Fi，我听说一些新的GData API可能会查找这个，这可能解释了您的400错误，您的应用程序可能没有与YouTube服务器进行通信。
