                if error == nil && image != nil {
                    // here the downloaded image is cached, now you need to set it to the imageView
                    DispatchQueue.main.async {
                        imageView.image = image

I had the same problem, and I tried to make:

SDWebImageDownloader *manager = [SDWebImageDownloader sharedDownloader];
[manager setValue:username forHTTPHeaderField:@"X-Oauth-Username"];

But the header were not send. After some tries, I came across the problem, SDWebImageDownloader at sharedDownloader makes a new instance of SDWebImageDownloader, so when you put the header at that instance, the instance that really downloads the image don't has the header.

I've solved making this:

SDWebImageDownloader *manager = [SDWebImageManager sharedManager].imageDownloader;
[manager setValue:username forHTTPHeaderField:@"X-Oauth-Username"];

I am using Basic authentication and setting the username and password on the sharedDownloader helped:

SDWebImageDownloader *downloader = [SDWebImageDownloader sharedDownloader];
downloader.username = @"username";
downloader.password = @"password";

I know it's pretty old but couldn't help to share what worked for me. I needed to set a login token value for header logintoken. So, this piece of code did what I wanted -

NSString *loginToken = // Some method to fetch login token    
[SDWebImageDownloader.sharedDownloader setValue:loginToken forHTTPHeaderField:@"logintoken"];
