GData Youtube Upload Crashing for iOS [closed]

I'm trying to use the GData objective c project v1.12.0 to upload a video to youtube. I followed the following guide to get GData linked with my project: http://mischneider.net/?p=377#comment-1277

It all seems to be linked properly, but I keep getting this error message:

2011-06-23 15:06:30.729[79217:207] * Assertion failure in -GDataServiceBase fetchObjectWithURL:objectClass:objectToPost:ETag:httpMethod:delegate:didFinishSelector:completionHandler:retryInvocationValue:ticket:, /Users/aalesia88/Desktop/VOKAL/Developement/SSB-Youtube/GData/BaseClasses/GDataServiceBase.m:603 2011-06-23 15:06:30.731[79217:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'GDataHTTPUploadFetcher needed'

Here is my methods used in calling the upload procedure:

    GDataServiceGoogleYouTube* service = nil;

    if (!service) {
        service = [[GDataServiceGoogleYouTube alloc] init];

        [service setServiceShouldFollowNextLinks:YES];
        [service setIsServiceRetryEnabled:YES];
    }

    SSBYoutubeCredentials *currentUser = [SSBYoutubeCredentials getCurrentUser];
    NSString *username = currentUser.username;
    NSString *password = currentUser.password;

    if ([username length] > 0 && [password length] > 0) {
        [service setUserCredentialsWithUsername:username
                                       password:password];
    } else {
        // fetch unauthenticated
        [service setUserCredentialsWithUsername:nil
                                       password:nil];
    }

    NSString *devKey = DEVELOPER_KEY;
    [service setYouTubeDeveloperKey:devKey];

    return service;
}

- (void)setUploadTicket:(GDataServiceTicket *)ticket 
{
    if (uploadTicket != nil) {
        [uploadTicket release];
    }

    uploadTicket = [ticket retain];
}

    SSBYoutubeCredentials *currentUser = [SSBYoutubeCredentials getCurrentUser];
    NSString *username = currentUser.username;

    NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username];

    // load the file data
    NSString *path;
#if !TARGET_IPHONE_SIMULATOR
    path = self.videoPath;

    path = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"m4v"];;
#endif
    NSData *data = [NSData dataWithContentsOfFile:path];

    // gather all the metadata needed for the mediaGroup

    GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup];
    [mediaGroup setMediaTitle:title];
    [mediaGroup setMediaDescription:desc];
    [mediaGroup addMediaCategory:category];
    [mediaGroup setMediaKeywords:keywords];
    [mediaGroup setIsPrivate:isPrivate];

    NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:path

    // create the upload entry with the mediaGroup and the file
    GDataEntryYouTubeUpload *entry;
    entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup

    GDataServiceTicket *ticket;
    ticket = [service fetchEntryByInsertingEntry:entry
                                      forFeedURL:url
                        开发者_如何学运维                delegate:self

    HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
    [self.navigationController.view addSubview:HUD];
    HUD.delegate = self;
    HUD.mode = MBProgressHUDModeDeterminate;
    HUD.labelText = @"Uploading...";

    [self setUploadTicket:ticket];
}

If anyone has any insight into this problem that would be very helpful.

Thanks, Anthony

The message is from GDataServiceBase.m. It indicates that the class GTMHTTPUploadFetcher is not linked in to your application.

The class may be missing due to the class file not being linked in the debug or release build target, or due to the preprocessor define GDATA_INCLUDE_YOUTUBE_SERVICE not being set, as described under "Removing Unneeded Code" at http://code.google.com/p/gdata-objectivec-client/wiki/BuildingTheLibrary

Yeah, it seemed to be a linking issue. I followed the instructions on that link to compile directly into my code and removed the classes I didn't need such as googledocs. Once I did that, everything built fine and I was able to upload.

Thanks for the help.
