How to create a UIImage with UIBezierPath

Question

I wrote some code to create a UIImage with UIBezierPath but it didn\'t work.

Can someone help me find out what\'s wrong with my code?

Answer 1

extension UIBezierPath {
    func shapeImage(view: UIView) -> UIImage! {

    // begin graphics context for drawing
    UIGraphicsBeginImageContextWithOptions(view.frame.size, false, UIScreen.main.scale)

    // configure the view to render in the graphics context
    //view.layer.render(in: UIGraphicsGetCurrentContext()!)

    // get reference to the graphics context
    let context = UIGraphicsGetCurrentContext()

    // translate matrix so that path will be centered in bounds
    context?.translateBy(x: -(bounds.origin.x - self.lineWidth), y: -(bounds.origin.y - self.lineWidth))
    // set color
    UIColor.black.setStroke()

    // draw the stroke
    stroke()

    // get an image of the graphics context
    let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()!

    // end the context
    UIGraphicsEndImageContext()

    return image
    }
}

first view with Bezier
