Show activity indicator in SDWebImage

Question

I\'m using SDWebView image and i want to show an Activity Indicator as placeholder, while fetching the image from remote.

I tried Malek\'s answer here How to show an act

Answer 1

Same code as above in SWIFT 4:

let activityIndicator = UIActivityIndicatorView.init(activityIndicatorStyle: UIActivityIndicatorViewStyle.gray)
    activityIndicator.center = addImage.center
    activityIndicator.hidesWhenStopped = true

    addImage.sd_setImage(with: URL(string: feed.image), completed: { (image: UIImage?, error: Error?, cacheType: SDImageCacheType, imageURL: URL?) in
        activityIndicator.removeFromSuperview()
    })

    addImage.addSubview(activityIndicator)
    activityIndicator.startAnimating()
