How to Circle the image

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:"https://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)
