带有 FireBase 的 SDWebImage [英] SDWebImage with FireBase

问题描述

我创建了以下函数来从 firebase 存储中获取图像:

I created the below function to fetch image from firebase storage:

func downloadImageFromFirebase(_ imageNameOnFireBase: String, imageViewToBeFilled: UIImageView) {
    let storage = Storage.storage()
    let reference: StorageReference = storage.reference().child(imageNameOnFireBase)
    reference.downloadURL { url , error in
        if error != nil {
            print(error!.localizedDescription)
            imageViewToBeFilled.image = UIImage(named: "default")
        } else {
            if let url = url {
                do {
                    let data = try Data.init(contentsOf: url)
                    imageViewToBeFilled.image = UIImage(data: data)
                } catch {
                    print("Error fetching URL")
                    imageViewToBeFilled.image = UIImage(named: "default")
                }
            }
        }
    }
} 

多次使用该功能会导致加载延迟，如何更快更可靠地下载图片?

When using the function many times it causes loading delay , How can i approach faster and more reliable way of downloading the images ?

推荐答案

您应该能够使用 URL 从 Firebase 获取图像，并且使用 SDWebImage 它将使您的应用程序具有非常快的加载和滚动时间，因为图像只是加载一次.可在此处找到有关此方面的出色教程:https://www.youtube.com/watch?v=XPAaxF0rQy0

You should be able to fetch images from Firebase with URLs, and using SDWebImage it will enable your app to have very fast loading and scrolling times as the images are only loaded once. An excellent tutorial for this can be found here: https://www.youtube.com/watch?v=XPAaxF0rQy0
