iOS YouTube Video Upload Error - objective-c

Question

I am trying to upload a video using Objective-C and YouTube API but it is not working and return error at last step. The error reads "User authentication required".
I am following this API document specifically the one which is without metadata. I got the authentication token with ClientLogin API
I checked authentication token with NSLog and it's there. I see the upload API also returns Upload URL but when I send HTTP PUT request to retrieved Upload URL, it returns an error mentioned above.
Here's Upload Code
- (bool) upload:(NSString *)file {
NSData *fileData = [NSData dataWithContentsOfFile:file];
NSURL *url = [NSURL URLWithString:self.UploadURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"PUT"];
[request setValue:#"Content-Type" forHTTPHeaderField:#"application/octet-stream"];
[request setValue:#"Content-Length" forHTTPHeaderField:[NSString stringWithFormat:#"%ud", [fileData length]]];
[request setHTTPBody:fileData];
NSError *requestError;
NSURLResponse *urlResponse = nil;
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];
NSLog(#"%#", [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]);
if (response == nil) {
return NO;
} else {
return YES;
}
}
I also tried the Direct Upload method but this always gives me Invalid Request error. Below is the code.
- (bool) directUpload:(NSString *)file {
NSString *title = [file lastPathComponent];
NSString *desc = #"This is test video.";
NSString *category = #"People";
NSString *keywords = #"video";
NSString *boundary = #"--qwerty";
NSString *xml = [NSString stringWithFormat:
#"<?xml version=\"1.0\"?>"
#"<entry xmlns=\"http://www.w3.org/2005/Atom\" xmlns:media=\"http://search.yahoo.com/mrss/\" xmlns:yt=\"http://gdata.youtube.com/schemas/2007\">"
#"<media:group>"
#"<media:title type=\"plain\">%#</media:title>"
#"<media:description type=\"plain\">%#</media:description>"
#"<media:category scheme=\"http://gdata.youtube.com/schemas/2007/categories.cat\">%#</media:category>"
#"<media:keywords>%#</media:keywords>"
#"</media:group>"
#"</entry>", title, desc, category, keywords];
NSData *fileData = [NSData dataWithContentsOfFile:file];
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:#"%#\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"Content-Type: application/atom+xml; charset=UTF-8\n\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[xml dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"%#\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"Content-Type: video/mp4\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"Content-Transfer-Encoding: binary\n\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:fileData];
[postBody appendData:[[NSString stringWithFormat:#"%#", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
NSURL *url = [NSURL URLWithString:#"http://uploads.gdata.youtube.com/feeds/api/users/default/uploads"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:[NSString stringWithFormat:#"GoogleLogin auth=\"%#\"", self.AuthToken] forHTTPHeaderField:#"Authorization"];
[request setValue:#"2" forHTTPHeaderField:#"GData-Version"];
[request setValue:[NSString stringWithFormat:#"key=%#", self.DeveloperKey] forHTTPHeaderField:#"X-GData-Key"];
[request setValue:[file lastPathComponent] forHTTPHeaderField:#"Slug"];
[request setValue:[NSString stringWithFormat:#"multipart/related; boundary=\"%#\"", boundary] forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%ud", [postBody length]] forHTTPHeaderField:#"Content-Length"];
[request setValue:#"close" forHTTPHeaderField:#"Connection"];
[request setHTTPBody:postBody];
NSError *requestError;
NSURLResponse *urlResponse = nil;
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];
NSLog(#"%#", [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]);
if (response == nil) {
return NO;
} else {
return YES;
}
}
