UIImageView extension

extension UIImageView {
  convenience init(named name: String, top: CGFloat, left:
    CGFloat, bottom: CGFloat, right: CGFloat) {
    let insets = UIEdgeInsetsMake(top, left, bottom, right) let originalImage = UIImage(named: name)
    let insetImage = originalImage?.withAlignmentRectInsets(insets) self.init(image: insetImage)
    } 
}
