SDWebImage + UITableViewCell, wrong image when scrolling?

Question

i\'m having an issue using SDWebImage to load images to a UIImageView inside a custom UITableViewCell. This is my code at the UITableView delegate:

    static NS         


        

Answer 1

I was getting blank images with the accepted answer and given the images I'm loading are small, I wanted to let the images cache in the background and not cancel the load.

1. Push a unique id on the stack before your closure and check it when your closure completes
2. prepareForReuse

Like this:

func updateArtistImage(url: URL) {
        let _eventId = self.event?.id
        SDWebImageManager.shared().loadImage(with: url, options: [], progress: nil) { (image, data, error, cacheType, finished, url) in
            if self.event!.id == _eventId {
                if error == nil {
                    self.artistImageView.image = image
                } else {
                    self.artistImageView.image = UIImage(named: "error_image")
                }
            }
        }
    }

and this:

override func prepareForReuse() {
    super.prepareForReuse()
    self.artistImageView.image = nil
}
