What is the method of implementing basic authentication in SDWebImage?

edit

To implement basic authentication in SDWebImage, you need to follow these steps:

1. Create an instance of SDWebImageDownloader.

2. Set the username and password properties of the downloader instance.

3. Create an instance of SDWebImageManager.

4. Set the downloader property of the manager instance to the downloader instance.

5. Use the manager instance to load the image using the normal SDWebImage API.

Here's the sample code:

// Create a downloader instance with credentials
SDWebImageDownloader *downloader = [SDWebImageDownloader sharedDownloader];
downloader.username = @"username";
downloader.password = @"password";

// Set downloader property of the manager instance
SDWebImageManager *manager = [SDWebImageManager sharedManager];
manager.downloader = downloader;

// Load the image using the manager instance
[manager loadImageWithURL:imageURL options:0 progress:nil completed:^(UIImage *image, NSData *data, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
  if (image) {
    // Do something with the loaded image
  }
}];
