Question

Hello I am using the SDWebImage framework in a project and I want to download and cache images, but I think my code is storing an image in the cache twice? Is there any way

Answer 1

Yes is possible to download the image using SDWebImage And store into local memory Manually.

Downloaded Image store into local memory using SDWebImage

func saveImage(url: URL, toCache: UIImage?, complation: @escaping SDWebImageNoParamsBlock) {
    guard let toCache = toCache else { return }

    let manager = SDWebImageManager.shared()
    if let key = manager.cacheKey(for: url) {
        manager.imageCache?.store(toCache, forKey: key, completion: complation)
    }
}

Load image from memory using image URL

static func imageFromMemory(for url: String) -> UIImage? {
    if let encoded = url.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed),
        let url = URL(string: encoded) {
        let manager = SDWebImageManager.shared()
        if let key: String = manager.cacheKey(for: url),
            let image = manager.imageCache?.imageFromMemoryCache(forKey: key) {
            return image
        }
    }
    return nil
}
