如何在UIView上插入图像？

UIImage在视图图层上添加

let myLayer = CALayer()
let myImage = UIImage(named: "star")?.cgImage
myLayer.frame = CGRect(x: 0, y: 0, width: 60, height: 60)
myLayer.cOntents= myImage
myView.layer.addSublayer(myLayer)

添加UIImage为子视图

let image = UIImage(named: "star")
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 0, y: 0, width: 60, height: 60)
myView.addSubview(imageView)
