How Add UIActivity Indicator on ImageView in swift using Alamofire Image

I am Using AlamofireImage library and i want to add a subview (UIActivityIndicator) on ImageView until image did not download. but have no idea how to do it.

self.imgView_main.af_setImageWithURL(downloadURL)

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()
    }
)
