How to Circle the image - ios

Question

Hello I am using SDWebImage in my app. This is my code to make the image in circle
extension UIImage {
var circle: UIImage? {
let square = CGSize(width: min(size.width, size.height), height: min(size.width, size.height))
let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
imageView.contentMode = .ScaleAspectFill
imageView.image = self
imageView.layer.cornerRadius = square.width/2
imageView.layer.masksToBounds = true
UIGraphicsBeginImageContext(imageView.bounds.size)
guard let context = UIGraphicsGetCurrentContext() else { return nil }
imageView.layer.renderInContext(context)
let result = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return result
}
}
copied it from here
I used to do images in cicle like this
let profilePicture = UIImage(data: NSData(contentsOfURL: NSURL(string:"http://i.stack.imgur.com/Xs4RX.jpg")!)!)!
profilePicture.circle
But Now As I am using SDWebImage its not working
cell.profileImageView.sd_setImageWithURL(UIImage().absoluteURL(profileImageUrl), placeholderImage: UIImage.init(named: "default-profile-icon")?.circle!)
Please let me know how can I make this extension work for SDWebImage

You can use the SDWebImageManager to download the image or take it from the cache and apply the circle in the completion block like this:
SDWebImageManager.sharedManager().downloadWithURL(NSURL(string:"img"), options: [], progress: nil) { (image:UIImage!, error:NSError!, cacheType:SDImageCacheType, finished:Bool) -> Void in
if (image != nil){
let circleImage = image.circle
cell.profileImageView.image = circleImage
}
}
Or you can use the version of the sd_setImageWithURL method that takes a completion block as a parameter
let completionBlock: SDWebImageCompletionBlock! = {(image: UIImage!, error: NSError!, cacheType: SDImageCacheType!, imageURL: NSURL!) -> Void in
if (image != nil){
let circleImage = image.circle
cell.profileImageView.image = circleImage
}
}
cell.profileImageView.sd_setImageWithURL(UIImage().absoluteURL(profileImageUrl), placeholderImage: UIImage.init(named: "default-profile-icon")?.circle!, completed: completionBlock)
