GDataServiceGoogleYouTube *service = [self youTubeService];
[service setYouTubeDeveloperKey:devKey];

NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:kGDataServiceDefaultUser];
// NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:clientID];


// load the file data

NSString *docDir = [searchPath objectAtIndex:0];
NSString  *path = [docDir stringByAppendingPathComponent:[shareVidArr objectAtIndex:0]];

Here's the complete example: https://github.com/youtube/yt-direct-lite-iOS/blob/master/YouTube%20Direct%20Lite%20for%20iOS/YouTubeUploadVideo.m

It uses Data API v3, which is the new API, GData will be deprecated really soon.
