image is downloading. but how to show UIActivityIndicator please help me


Solution

  • You can use completion: function for that, First start the activityIndicator and stop the indicator when you get the image in completion block like this.

    self.activityIndicator.startAnimating()
    self.listImageView.af_setImageWithURL(
        NSURL(string: list!.image!)!,
        placeholderImage: nil,
        filter: nil,
        imageTransition: .CrossDissolve(0.5),
        completion: { response in
            let image = response.result.value // UIImage Object
            self.activityIndicator.stopAnimating()
        }
    )
