I want to ask a question about the UIview on the iPhone applicaiton. I want to display a image one the UIView programmatically, but I don't know how to do it. What should I do to display the image. Thank you very much.

The first step is to drag the UIImageView onto your view. Then open the UIImageView properties pane and select the image asset (assuming you have some images in your project). You can also configure how the underlying image is scaled to fit inside the UIImageView.
extension UIView { // Using a function since `var image` might conflict with an existing variable // (like on `UIImageView`) func asImage() -> UIImage { if #available(iOS 10.0, *) { let renderer = UIGraphicsImageRenderer(bounds: bounds) return renderer. image { rendererContext in layer. render(in: rendererContext.
First you create a UIImage from your image file, then create a UIImageView from that: let imageName = "yourImage. png" let image = UIImage(named: imageName) let imageView = UIImageView(image: image!)
It's very easy just assign CGImageRef to view's layer's content, eg:
layerView.layer.contents = UIImage(named: "Mario.png")?.cgImage
