How Do I Take a Screen Shot of a UIView?

Question

I am wondering how my iPhone app can take a screen shot of a specific UIView as a UIImage.

I tried this code but all I get is a blank image

I have created usable extension for UIView to take screenshot in Swift:

extension UIView{

var screenshot: UIImage{

    UIGraphicsBeginImageContext(self.bounds.size);
    let context = UIGraphicsGetCurrentContext();
    self.layer.renderInContext(context)
    let screenShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenShot
}
}

To use it just type:

let screenshot = view.screenshot
