how can I get the data of cached images SDWebImage

Question

I\'m using SDWebImage library to cache web images in my UICollectionView:

cell.packItemImage.sd_setImage(with: URL(string: smileImageUrl[indexPath.row]))

SDWebImage caches downloaded images automatically by default. You can use SDImageCache to retrieve images from the cache. There is a memory cache for the current app session, which will be quicker, and there is the disk cache. Example usage:

if let image = SDImageCache.shared().imageFromDiskCache(forKey: imageURL.absoluteString) {
//use image
}

if let image = SDImageCache.shared().imageFromMemoryCache(forKey: imageURL.absoluteString) {
//use image
}

Also make sure you import SDWebImage in your file. (If you're using Swift/Carthage, it will be import WebImage
