Objective c iOS YouTube视频上载错误

我正在尝试使用Objective-C和YouTube API上传视频，但它不工作，并在最后一步返回错误。错误显示为“需要用户身份验证”

我特别关注这个没有元数据的问题。我得到了身份验证令牌

我用NSLog检查了身份验证令牌，它就在那里。我看到上传API也返回上传URL，但当我向检索到的上传URL发送HTTP PUT请求时，它返回上面提到的错误

这是上传代码

- (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;
    }
}

我还尝试了直接上传方法，但这总是给我无效请求错误。下面是代码

- (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\"?>"

                     @"<media:description type=\"plain\">%@</media:description>"

                     @"</media:group>"
                     @"</entry>", title, desc, category, keywords];
