- Fetch security image URL. In order to protect image resources, instead of using a pernement image url, using a temporary security url only valid for short seconds. imageManager:fetchSecurityURL: is used to handle this situation.
#import <SDWebImage/UIImageView+WebCache.h>

SDWebImageManager.sharedManager.delegate = self;
- (nullable NSURL *)imageManager:(nonnull SDWebImageManager *)imageManager fetchSecurityURL:(nullable NSURL *)imageURL {

return tempURL;
}
[imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
