How to capture UIView to UIImage without loss of quality on retina display

My code works fine for normal devices but creates blurry images on retina devices.

Does anybody know a solution for my issue?

Answer 1

All Swift 3 answers did not worked for me so I have translated the most accepted answer:

extension UIImage {
    class func imageWithView(view: UIView) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0.0)
        view.layer.render(in: UIGraphicsGetCurrentContext()!)
        let img: UIImage? = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img!
    }
}
