从Firebase缓存图片 [英] Cache Image from Firebase

问题描述

我有多个单元格，当前拥有Firebase中的不同照片。每当用户加载这些图像，然后滚动，它们被重新下载，快速吃掉数据。我发现这与任何有计量数据计划的用户有关。我能做些什么来解决这个问题？ Firebase是否提供任何选项来缓存下载的图片？

这是我目前将图片调入单元格的方式：

  if let imageName = post [image] as？字符串{
 let imageRef = FIRStorage.storage（）。reference（）。child（images / \（imageName））
 imageRef.data（withMaxSize：25 * 1024 * 1024，completion：{ （data，error） - >如果错误== nil {
 let image = UIImage（data：data！）
 cell.postImageView.image = image 
  











$ $ p $ let url = URL（string：url_of_your_image）
imageView.kf.setImage（with：url）





I have multiple cells that currently hold different photos from Firebase. Every time a user loads these images then scrolls, they are re-downloaded which eats up data fast. I find this concerning to any user who has a metered data plan. What could I do to solve this? Does Firebase offer any options to cache downloaded images?

This is how I am currently calling an image into a cell:

if let imageName = post["image"] as? String {
        let imageRef = FIRStorage.storage().reference().child("images/\(imageName)")
        imageRef.data(withMaxSize: 25 * 1024 * 1024, completion: { (data, error) -> Void in if error == nil {
            let image = UIImage(data: data!)
            cell.postImageView.image = image

解决方案

Use Kingfisher to cache images. It's light and very easy to use. Just pass your url from firebase and it will automatically cache it.

let url = URL(string: "url_of_your_image")
imageView.kf.setImage(with: url)
