class ViewController: UIViewController, DrawableViewDelegate { @IBOutlet var drawableView: DrawableView! { didSet { drawableView.delegate = self drawableView.strokeColor = .blue drawableView.strokeWidth = 12.0 drawableView.transparency = 1.0 } } func setDrawing(_ isDrawing: Bool) { /* Run some logic based on if the user is currently drawing a stroke or not. Commonly people hide the drawing tools UI while the user is drawing and fade it back in once they stop. */ } func saveDrawingToPhotoLibrary() { guard let drawnImage = drawableView.image else { return } UIImageWriteToSavedPhotosAlbum(drawnImage, self, nil, nil) } }
