[iOS] UIButton title , image vertical align 하기

func alignTextBelow(spacing: CGFloat = 8.0) {
        guard let image = self.imageView?.image else {
            return
        }

        guard let titleLabel = self.titleLabel else {
            return
        }

        guard let titleText = titleLabel.text else {
            return
        }

        let titleSize = titleText.size(withAttributes: [
            NSAttributedString.Key.font: titleLabel.font as Any
        ])

        titleEdgeInsets = UIEdgeInsets(top: spacing, left: -image.size.width, bottom: -image.size.height, right: 0)
        imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: 0, bottom: 0, right: -titleSize.width)
    }

UIButton를 extesion해서 안에 넣어두고 사용하면 편리하다😳
