UIImageViewとその境界線の間にパディングを追加するにはどうすればよいですか?
Img.layer.cornerRadius = Img.bounds.width / 2
Img.layer.borderWidth = 2
Img.layer.borderColor = UIColor.blue.cgColor
Img.clipsToBounds = true
このような:
このリンク のとおり
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let image = UIImage(named: "imagename")!
let imageView = UIImageView(image: image.imageWithInsets(insets: UIEdgeInsetsMake(30, 30, 30, 30)))
imageView.frame = CGRect(x: 0, y: 0, width: 300, height: 400)
imageView.backgroundColor = UIColor.gray
imageView.layer.borderWidth = 2
imageView.layer.borderColor = UIColor.blue.cgColor
view.addSubview(imageView)
}
}
extension UIImage {
func imageWithInsets(insets: UIEdgeInsets) -> UIImage? {
UIGraphicsBeginImageContextWithOptions(
CGSize(width: self.size.width + insets.left + insets.right,
height: self.size.height + insets.top + insets.bottom), false, self.scale)
let _ = UIGraphicsGetCurrentContext()
let Origin = CGPoint(x: insets.left, y: insets.top)
self.draw(at: Origin)
let imageWithInsets = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return imageWithInsets
}
}
