Circular UIImageView in UITableView without performance hit?

Question

I have a UIImageView on each of my UITableView cells, that display a remote image (using SDWebImage). I\'ve done some QuartzCore

Answer 1

In Swift use this Extension for CircularImageView or RoundedImageView :

extension UIView {

    func circular(borderWidth: CGFloat = 0, borderColor: UIColor = UIColor.whiteColor()) {
        let radius = CGRectGetWidth(self.bounds) / 2
        self.layer.cornerRadius = radius
        self.layer.masksToBounds = true

        self.layer.borderWidth = borderWidth
        self.layer.borderColor = borderColor.CGColor
    }

    func roundedCorner(borderWidth: CGFloat = 0, borderColor: UIColor = UIColor.whiteColor()) {
        let radius = CGRectGetWidth(self.bounds) / 2
        self.layer.cornerRadius = radius / 5
        self.layer.masksToBounds = true

        self.layer.borderWidth = borderWidth
        self.layer.borderColor = borderColor.CGColor
    }

}

Usage:

self.ImageView.circular()
self.ImageView.roundedCorner()
